I have successfully flashed a ESP-WROOM-32 with the DIY v1 version of meshastatic firmware using Platform.io/Vscode. I have disabled the onboard 0.96 inch oled display. i have edited to firmware to enable my 128 x 128 SH1107 tft display, I also had to use the SEEED variant constructor for SH1107 128×128 in the firmware to get the display to work properly.  I have repeated this process with the ESP32-S3-Uno using the Heltec v3 firmware. I am waiting for my SX series chip sets to arrive to attempt to get the ESP,s working with LoRa.
