USB programming adapter for AVR-ISP, AVR-UPDI, STM32, LPC, ESP8266, ESP32
Connection of an ESP Controller
DIP SWITCH: 2 = OFF, 3 = OFF, 4 = ON
NOTICES, TIPS:
The RST pin of the ESP8266, or the EN-Pin of the ESP32 respectively, should be placed against +3.3V with a 10
kOhm resistor. A capacitor to ground (as recommended in many circuits) must not be on this pin because the RESET
is controlled by the EXA-PROG.
In order to program the ESP8266 or ESP32, it must be supplied with 3.3 volts. If the current consumption is not higher
than 300mA, then the controller, including the circuitry, can also be supplied from the EXA-PROG.
When using ESPTOOL, the control lines GPIO0 and RESET are activated automatically. A manual activation of the
bootloader is therefore not necessary. However, activation can also be triggered using the reset button on the EXA-
PROG if this does not work via the software.
Adapter 10-pin to ESP
Socket strip for ESP-01 modules, pin headers for the connection of ESP8266 or ESP32
controllers via jumper cables.
(optional accessories, not included with the EXA-PROG)
Connect the programming connector leads on the EXA-PROG directly to
the pins on the controller or on an ESP8266 or ESP32 module respectively:
10 Pin Header
PIN1 (TXD)
PIN3 (GPIO0)
PIN5 (RESET)
PIN9 (RXD)
PIN10 (GND)
optional:
PIN2 (VCC)
DIP switch 1: must be set to OFF = 3.3V.
