SWITCH 1: Voltage Level
3.3V
5V
Notices:
The maximum load on the programming port is 500mA at 5 volts and 300mA at 3.3 volts. If more power is required,
please supply the connected circuit with external voltage and do not connect PIN2 on the programming connector.
The external circuit must always be operated with the same voltage as the voltage set on the programmer with DIP
switch 1.
GND must always be connected to the circuit in which the controller to be programmed is located.
Please note that almost all 32-bit microcontrollers may only be operated with 3.3V and to do this, DIP switch 1 must be
set to OFF. The controller can be destroyed if they are operated with 5V.
2 = ON, 3 = ON, 4 = OFF
Programmer for ESP8266 and ESP32 with ESPTOOL
The ESP8266 and ESP32 are programmed via the integrated bootloader via the lines TXD0 and
RXD0. In order to activate the bootloader automatically the lines GPIO0 und RESET (EN) are also
required.
Please DIP1 = OFF, set programming voltage to 3.3V!
1 = OFF
There is a voltage of 3.3V at PIN 2 of the 10-pin programming connector. All signal levels on the
programming lines have a maximum voltage of 3.3V.
1 = ON
There is a voltage of approx. 5V at PIN 2 of the 10-pin programming connector. All signal levels
on the programming lines have a maximum voltage of approx. 5V.
Please note that the exact voltage value may vary and depends on the voltage at the USB port.
This value can fluctuate depending on the load and it can be between 4.5V and 5.2V. However,
this is usually negligible when microcontrollers are being programmed.
