ESP Radio Interface - Through Hole version with ESP32 DOIT devboard (based on ESPRI project)
ESPRI project provides an integrated Digital Audio / Programming Interface for Quangsheng UV-K5, Baofeng UV-5R and other Kenwood-style connector radios, similar to the excellent AIOC project. With ESP32 offering WiFi/Bluetooth connectivity, the possibilities are endless !
Since Lolin32 Lite is not common in this part of the world and SMD sourcing / assembly is still cumbersome, we've attempted a Through Hole version for the most common 30 pin ESP32 DOIT board.
Changes:
- Since there are a lot of unpopulated I/Os, we've added 0.91" OLED, couple of LEDs, Switches and one more Touchpad Button.
- The ADC/DAC IO pins have been broken out to a header
- Header Pins for Radio PWR, 5v and 3.3v
- SMD 2N7002 has been replaced with THT 2N7000
