4 Channel IIC I2c Logic Level Converter Bi-Directional Module 5V to 3.3V Arduino
$3.49 - $4.10 Inc. GST
If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The CJMCU bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This
ADS1115 ADC 4 Channel 16Bit I2C PGA Low Power Arduino Raspberry Pi 2 ESP8266 PIC
$7.57 - $8.90 Inc. GST
Our ADS1115 based ADC module is perfect for microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC. The module provides 16-bit precision at 860 samples/second over I2C (2 Wire Bus). The onboard ADS1115 can be configured as 4 single-ended input channels, or two differential channels and includes
