The Universal TTL-Programmer Version-2 With TYPE-C Socket is an upgraded, high-performance serial programming and debugging module designed to provide seamless USB-to-UART TTL communication for a wide array of microcontrollers. Featuring a modern Type-C USB interface, this Version-2 programmer delivers stable power supply and high-speed data transmission required for modern embedded systems development.
Equipped with selectable 3.3V and 5V operating voltage levels via onboard jumpers or switches, the module provides flexible logic compatibility for power-sensitive wireless modules like ESP32 and ESP8266 as well as standard 5V microcontrollers. Integrated automatic boot and reset circuitry (DTR/RTS auto-download logic) allows single-click firmware uploading directly from popular IDEs without requiring manual press of reset or boot buttons.
This universal programmer is widely used for uploading custom firmware, serial debugging, unbricking hardware devices, and interfacing microcontrollers with desktop computers. It features standard 2.54mm pitch header pins (V_CC, GND, TXD, RXD, DTR, RTS) that seamlessly connect to breadboards, perfboards, and prototyping wire assemblies.
