Tiny4FSK

high-altitude balloon flight computer with tracking

[OUT OF STOCK RIGHT NOW, MORE COMING NEXT MONTH] Tiny4FSK is a radio transmitter board that sends live telemetry over long distances and altitudes using 4FSK modulation. It is designed to be used on high-altitude balloons, drones, and rockets to receive GPS position, temperature, pressure, and humidity in real time from the ground. It uses the SAMD21 microcontroller flashed with the Arduino bootloader, Si4463 sub-GHz radio module, BME280 environmental sensor, and the ATGM336H module for GPS. It can last around 15 hours with the right settings on a single AA battery. It's also flown on around 10 full HAB flights successfully! [AMATEUR RADIO LICENSE REQUIRED TO OPERATE. AT LEAST TECHNICIAN IN THE US.]
