How do I wire the DY50 to an Arduino?
Connect VCC and GND to a supply within 3.6 V to 6.0 V. Cross the serial lines: module TX goes to Arduino RX, and module RX goes to Arduino TX (or to SoftwareSerial pins). Check the module's logic level before connecting it directly to a 3.3 V board.
Can I use the DY50 with an ESP32?
It uses standard UART TTL signalling, so it can connect to an ESP32 UART. The ESP32 works at 3.3 V logic, so use a level shifter if the module outputs 5 V logic.
