Good news from OpenLRS (Opensource Long Range System) project!
Today i received 7 watt RF booster chips and at last i'm ready to finishing the PCB designs. This weekend i will finish the booster design and PCBs will be ready in 3 weeks.
Here is the latest PCB designs of Tx, Rx and IMU modules of OpenLRS
Tx and Rx modules size smaller than most of RC modules. Rx module including I2C (or 3 adc) conector pads on back side. I'm planning to connect my new 6DOF IMUnext v3 board there. Rx can stabilize the plane (or quadro) without any external parts and it sends the parameters to the ground over telemetry system. And Rx's rs232 port already available for digital telemetry or direct GPS connection.
Some advantages of OpenFARC:
I'm developing OpenLRS project with AVR-GCC on Atmega328 chipset. All ATMEL developers are welcome ;)
