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.

Crowtail – RTC 2.0
If you want to make your own electronic watch a RTC module is necessary to generate you the right time, with very low power consumption. This tiny RTC module is based on the clock chip DS1307 which communicates with microcontrollers with I2C protocol. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. This module is really low power consumption, it can serves you more than a month with a CR1220 battery.

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 – Temperature and Humidity Sensor 2.0
This module can help you detect the temperature and humidity of the environment of your house. The module contains a DHT11 Temperature and Humidity sensor that is a complex sensor with a calibrated digital signal out. It uses digital module acquisition technology and the temperature & humidity sensor technology. The sensor consists of a resistance-type moisture element and an NTC temperature measuring element. Because of the single-wire serial interface, it is easy to use the module.
- -Work Voltage: 3.3 Volt ~ 5 Volt
- -Measuring Range: Humidity: 20% – 90% RH
- -Measuring Range: Temperature: 0 ~ 50 °C
- -Signal Collecting Period: 2S
- -Accuracy: Humidity: ±5% RH
- -Accuracy: Temperature: ±2°C

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 – Rotary Angle Sensor 2.0
This rotary angle sensor may also be known as potentiometer that produces analog output between 0 and 3.3-5 Volt. The angular range is 300 degrees with a linear change in value. The resistance value is 10k ohms, perfect for Arduino use. Some applications like smart light control, volume control, only you can not think of things, no impossible things.

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.

Crowtail Moisture Sensor 2.0
This Moisture Sensor can be used to detect the moisture of soil and thus to monitor if the plants in your garden need some water. This sensor uses the two probes to pass current through the soil, and then it reads then resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance). Compares to the other moistures sensor using the same moisture test method, this module has super long legs, making it suitable for actual applications. This Moisture Sensor can be used to detect the moisture of soil or your pet plant’s water level, let the plants in your garden reach out for human help.
Crowtail – I2C LCD
A new crowtail for LCD1602, it contains LCD1602 and MCP23008 module. Unique interface for crowtail. Provide convenience to work with a LCD.
