Description of ESP8285/ESP8266/ESP32 Burning:
powered by:5V direct connection (6V2A fuse) / DC-DC Buck circuit 5V to 3.3V high current outputProgrammable:GD32F150G8 32-bit Cortex-M3 MCU onboardUSB interface:USB Type-Cinterface:2x6P 2.54mm pitch curved pin
Precautions:
1.Because the original intention of this module design is to program the chips such as Kendryte K210 and Espressif ESP8266 / ESP8285 / ESP32, the level of BOOTx and RSTx of the interface is directly controlled by DTR / RTS. DTR / RTS does not follow RS- 232 definitions.2.Correspondence between DTR / RTS and RST / BOOTUART0: DTR controls RST0, RTS controls BOOT0UART1: DTR controls BOOT1, RTS controls RST13.Output modeBOOT0 push-pull output 3.3V; RST0 is open-drain outputBOOT1 and RST1 are both open-drain outputs
