Mode: Editors' pick
Based on a popular open source radio express LRS data collation.
The hardware prototype is jumper r900mini, with the measure of area 23mm * 16mm. All components are packaged in 0603 package, which reduces the difficulty of welding and ensures the minimum cost.
Rfm95 module, stm32f103c8t6, ircuit verification has passed
