The CJMCU-4051 is a breakout board for the 74HC4051 8-Channel Analog Multiplexer/Demultiplexer IC. It allows a single microcontroller analog or digital pin to interface with up to 8 channels, selected via 3 digital address pins (S0, S1, S2). Ideal for expanding the ADC inputs of Arduino, ESP32, and other microcontrollers. Supports both analog and digital signal routing in either direction.
Features:
- IC: 74HC4051 (SP8T — Single Pole, 8 Throw)
- Channels: 8 analog/digital (bidirectional)
- Address select pins: S0, S1, S2 (3-bit binary selection)
- Analog input voltage range: ±5V
- ON resistance: 80Ω @ 4.5V | 70Ω @ 6V | 60Ω @ 9V
- Logic level translation: 5V digital ↔ ±5V analog signals
- Enable pin (E): disables all switches when HIGH
- Board size: 30 × 19mm
- Compatible with Arduino, ESP32, Raspberry Pi
