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.

Crowtail – GPS
This Crowtail – GPS module is a cost-efficient and field-programmable gadget armed with a NEO-6M-0-001 and serial communication configuration. It features 55 channels, and a GPS L1 C/A code receiver. The sensitivity of tracking and acquisition both reach up to -161dBm, making it a great choice for personal navigation projects and location services, as well as an outstanding one among products of the same price class.
- -Input Voltage: 5 Volt
- -Supports NMEA and U-Blox Binary
- -Low power consumption
- -Baud rates configurable

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.

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.

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.

Pololu 5 Volt Step-Up Voltage Regulator U1V10F5
This tiny U1V10F5 switching step-up voltage regulator efficiently generates 5 Volt from input voltages as low as 0.5 Volt. Unlike most boost regulators, the U1V10F5 automatically switches to a linear down-regulation mode when the input voltage exceeds the output.
Ultrasonic Distance Sensor – HC-SR04 (5 Volt)
This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2 Centimetres to 400 Centimetres of non-contact measurement functionality with a ranging accuracy that can reach up to 3 Millimetres. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit. There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). This sensor has additional control circuitry that can prevent inconsistent “Bouncy” data depending on the application.

SparkFun 9DoF IMU Breakout – LSM9DS1
The SparkFun LSM9DS1 Breakout is a versatile, motion-sensing System-In-A-Chip. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer, nine degrees of freedom (9DOF) on a single board. The LSM9DS1 from STMicroelectronics is equipped with a digital interface, but even that is flexible. This IMU-In-A-Chip is so cool we put it on the quarter-sized breakout board you are currently viewing.
The LSM9DS1 is one of only a handful of IC’s that can measure three key properties of movement, angular velocity, acceleration, and heading, in a single IC. By measuring these three properties, you can gain a great deal of knowledge about an object’s movement and orientation. The LSM9DS1 measures each of these movement properties in three dimensions. That means it produces nine pieces of data: acceleration in x/y/z, angular rotation in x/y/z, and magnetic force in x/y/z. The LSM9DS1 Breakout has labels indicating the accelerometer and gyroscope axis orientations, which share a right-hand rule relationship with each other.

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. This 56-Channel GPS module, that supports a standard NMEA-0183 and uBlox 7 protocol, has low power consumption of 40mA@3.3V (max), an antenna on board, and -162dBm tracking sensitivity. With 56 channels in search mode and 22 channels “All-In-View” tracking, the GP-20U7 is quite the work horse for its size.

GPS Receiver – GP-20U7 (56 Channel)
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. With 56 channels in search mode and 22 channels “All-In-View” tracking, the GP-20U7 is quite the work horse for its size.
