Programmers — buying guide

What is in this category

10 products: CP2102 USB-TTL Converter (USB-UART Converter), CH340G USB-TTL Converter (USB-UART Converter), RS232-TTL Converter/MAX3232 (Serial Interface Module), MAX485 TTL RS485 Converter, MCP2515 CAN BUS-SPI Communication Module, USB-RS485 TTL Converter (FT232), TTL RS485 Converter (UART RS485), IIC I2C 5V-3.3V Logic Level Converter and more.

How to choose

  • CH340G USB-TTL — the cheapest UART adapter, 5V/3.3V switch; Pro Mini, ESP8266, GPS module tests.
  • CP2102 — more stable, driver-free on Mac and Linux; most ESP32/ESP8266 boards use this very chip.
  • ST-Link V2 — STM32 and STM8 programming and debug (SWD); with STM32CubeProgrammer.
  • BIOS SPI cable (SOP8 clip) — read/write 25xx flash without desoldering; laptop repair.
  • MAX485 / USB-RS485 — industrial lines up to 1200 m, Modbus RTU; MCP2515 — automotive CAN.
  • Logic level shifter — 4-channel bidirectional 5V↔3.3V, works for I2C too.

Compatibility

All work with the Arduino IDE / PlatformIO; USB devices are auto-detected on Windows 10/11 (except CH340 — driver in our lessons).
