MicroSD Card Module
There are different microSD card modules compatible with the ESP32. We’re using the microSD card module it communicates using SPI communication protocol. You can use any other microSD card module with an SPI interface. This microSD card module is also compatible with other microcontrollers like the Arduino boards. To learn how to use the microSD card module with the Arduino. You can connect it to the ESP32 using the default SPI pins.

Global Positioning System (GPS)
The Global Positioning System (GPS) is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals.
GPS Receiver – GP-20U7
The GP-20U7 is a compact GPS receiver with a built-in high performances All-In-One GPS chipset. The GP-20U7 accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability.

Adafruit DS3231 Precision RTC FeatherWing
This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator to any Feather main board. This RTC is the most precise you can get in a small, low power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that’s all well and good, but those crystals have slight drift, particularly when the temperature changes (the temperature changes the oscillation frequency very very very slightly but it does add up!) This RTC is in a beefy package because the crystal is inside the chip! And right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule. With a CR1220 12mm coin cell plugged into the top of the FeatherWing, you can get years of precision timekeeping, even when main power is lost. Great for datalogging and clocks, or anything where you need to really know the time.

EEPROM
EEPROM (Electrically Erasable Programmable Read-only Memory) is a type of non-volatile memory. EEPROM is a type of non-volatile ROM that enables individual bytes of data to be erased and reprogrammed. That is why EEPROM chips are known as byte erasable chips. EEPROM is usually used to store small amounts of data in computing and other electronic devices. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.
The microcontroller on the Arduino boards have 512 bytes of EEPROM: memory whose values are kept when the board is turned off. Functions in the EEPROM class are automatically included with the platform for your board, meaning you do not need to install any external libraries. The supported microcontrollers on the various Arduino have different amounts of EEPROM: 1024 bytes on the ATmega328P, 512 bytes on the ATmega168 and ATmega8, 4 KB (4096 bytes) on the ATmega1280 and ATmega2560. The Arduino boards have an emulated EEPROM space of 1024 bytes. The EEPROM library on ESP32 provides a reliable way to store data persistently, so that it remains accessible even when the power supply is disconnected. Unlike RAM, the data we save with the EEPROM library does not get lost when power is cut. This feature makes it an ideal choice for retaining configurations, settings, and other important data in embedded devices like the ESP32.

Crowtail – 3-Axis Digital Compass
Crowtail-3-Axis Compass module, a member of Crowtail family uses I²C based Honeywell HMC5883L digital compass. This ASIC is equipped with high resolution HMC118X magneto-resistive sensors and a 12-bit ADC. It provides compass heading accuracy up to 1° to 2°. Signal conditioning like amplification, automatic degaussing strap drivers and offset cancellation are inbuilt. This Crowtail module also includes a XC6206P332MR for power supply requirement. Hence user can connect any 3.3V to 6V DC power supply.
- -Crowtail compatible interface
- -3-Axis Magneto-resistive type sensors
- -I²C serial interface
- -1° to 2° Degree heading accuracy
- -Up to 116 Hz Maximum output rate
- -Built-In self test
- -Low cost compassing
- -Magnetometry
- -Pedestrian navigation
- -Hobby auto navigation
- -Compassing support for mobile devices and portable computers

Crowtail – 3-Axis Digital Accelerometer
Crowtail – 3-Axis Digital Accelerometer with specific Crowtail interface, It’s base on an advanced 3-axis IC ADXL345. This is a high resolution digital accelerometer providing you at max 3.9mg/LSB resolution and large ±16g measurement range. Have no worry to implement it into your free-fall detection project, cause it’s robust enough to survive up to 10,000g shock. Meanwhile, it’s agile enough to detect single and double taps. It’s ideal for motion detection, gesture detection as well as robotics. This digital 3-axis accelerometer has excellent EMI protection.
Its variable output makes it suitable for a wide range of applications:
- 1. HDD shock protection
- 2. Vibration sensor
- 3. Game controller input
- 4. Robotics
- 5. Smart vehicles
- 6. Anywhere you need to obtain motion-sensing and orientation information.
- 7. The excellent sensitivity provide high-precision output up to ±16g.

Pololu AltIMU-10 v5 Gyro, Accelerometer, Compass, and Altimeter
The Pololu AltIMU-10 v5 is a compact board that combines ST’s LSM6DS33 3-axis gyroscope and 3-axis accelerometer, LIS3MDL 3-axis magnetometer, and LPS25H digital barometer to form an inertial measurement unit (IMU) and altimeter. These sensors are great ICs, but their small packages make them difficult for the typical student or hobbyist to use. They also operate at voltages below 3.6 Volt, which can make interfacing difficult for microcontrollers operating at 5 Volt. The AltIMU-10 v5 addresses these issues by incorporating additional electronics, including a voltage regulator and a level-shifting circuit, while keeping the overall size as compact as possible. The board ships fully populated with its SMD components, including the LSM6DS33, LIS3MDL, and LPS25H.
Attitude and Heading Reference System (AHRS)
An attitude and heading reference system (AHRS) uses an inertial measurement unit (IMU) consisting of microelectromechanical system (MEMS) inertial sensors to measure the angular rate, acceleration, and Earth’s magnetic field. These measurements can then be used to derive an estimate of the object’s attitude. An AHRS typically includes a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer to determine an estimate of a system’s orientation. Each of these sensors contribute different measurements to the combined system and each exhibit unique limitations.

SparkFun Tri-Axis Gyroscope – L3G4200D
This is a breakout board for the L3G4200D low-power three-axis angular rate sensor. The L3G4200D is a MEMS motion sensor and has a full scale of dps and is capable of measuring rates with a user-selectable bandwidth. These work great in gaming and virtual reality input devices, motion control with MMI, GPS navigation systems, appliances and robotics. The L3G4200D is a low-power three-axis angular rate sensor able to provide unprecedented stablility of zero rate level and sensitivity over temperature and time. It includes a sensing element and an IC interface capable of providing the measured angular rate to the external world through a digital interface.

SparkFun Triple Axis Magnetometer Breakout – HMC5883L
This is a breakout board for Honeywell’s HMC5883L, a 3-axis digital compass. Communication with the HMC5883L is simple and all done through an I2C interface. There is no on-board regulator, so a regulated voltage of 2.16-3.6VDC should be supplied. The breakout board includes the HMC5883L sensor and all filtering capacitors as shown. The power and 2-wire interface pins are all broken out to a 0.1 inch pitch header.
