The CH34X family comprises widely used USB‑to‑serial chips manufactured by WCH (WinChipHead), commonly integrated into generic UNO R3, ESP8266, and ESP32 development boards.
Overview
- 24-DIGIT COMPLETE DISPLAY KIT Includes 12 common cathode and 12 common anode 0.56" single-digit 7-segment LED displays — 24 digits total for clocks, counters, timers, scoreboards, and sensor readouts.
- 12 PRE-BUILT 74HC595 DRIVER BOARDS WITH INTEGRATED RESISTORS Pre-assembled 74HC595 shift register modules remove the need for individual current-limiting resistors, reducing wiring and simplifying breadboard prototyping. Each board is breadboard-ready.
- CONTROL MULTIPLE DIGITS WITH JUST 3 PINS Daisy-chain shift register boards to drive multiple digits using only 3 microcontroller pins (Data, Clock, Latch). Build 4-digit clocks, 6-digit timers, or larger scoreboards without exhausting GPIO. Compatible with Arduino's shiftOut() function.
- 24 SNAP-FIT 3D-PRINTED ENCLOSURES INCLUDED Every digit comes with a matching 3D-printed snap-on case for a finished look while protecting the LED d... Read More...
