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
- 3 x NANO V3.0 BOARDS ATmega328P AT 16MHZ: 32KB Flash, 2KB SRAM, 1KB EEPROM, 14 digital I/O with 6 PWM, and 8 analog inputs. Reversible USB Type-C connector, so no more flipping the plug and no special cable to keep track of.
- SEE EVERY I/O PIN STATUS LED ON EACH ONE: TX/RX, D2-D13 and A0-A7 all get an indicator on the PinPulse Shield. Check HIGH or LOW at a glance instead of reaching for a multimeter or filling the serial monitor with print statements.
- BUFFERED, NON-INTRUSIVE SN74HC04D HEX INVERTERS: the LEDs are driven through buffers rather than tapped straight off the pin, keeping the load off your signals so I2C, SPI and UART timing stays clean.
- MALE AND FEMALE ON EVERY PIN DUAL-GENDER 2.54MM HEADERS: male-to-male, male-to-female and female-to-female jumper wires all plug straight in. No adapters, no hunting through the box for the right cable.
