Hi, I have a project to connect the ESP32 to the EML327 directly via UART communication and remove the Bluetooth module. Does anyone know the pin configuration for RX, TX, VCC, and ground on this Bluetooth module that i circle ?
I have marked the UART pins in the image (according to the YC1021 datasheet)
You can use a multimeter to identify them on the edge of the board.
