Most of our testers use pretty simple gpio toggling to verify everything's connected - but for our Radio Feathers https://lnkd.in/gsrgRF9C we want to also verify that the radio signal is connected through properly. so we use a separate radio to ping pong a message and check the RSSI. traditionally we did this with separate radio feathers but that got a little annoying to manage since they'd get lost or the battery would be dead just as we were about to get on with some testing. since our new fancy Tester Brains https://lnkd.in/eGCQmvnt got an upgrade from teensy to pico, we also revised to add an EYE-SPI connector which brings plenty of GPIO and SPI over. now we have the second RFM module connected to the tester itself so it's all-in-one. a lot easier to manage!
