Description:
This module converts power supply voltage and signal voltage such as I2C, UART, etc. It has Grove-compatible and Qwiic-compatible connectors. It allows bidirectional connection of 3.3V system and 5V system. It supports the following 4 voltage conversion patterns.
Specifications:
- Maximum data rate
- Open drain (ex. I2C): 2 Mbps)
- Push-pull (ex. UART): 24 Mbps
- Maximum output current
- 5V → 3.3V: 1.0 A
- 3.3V → 5V: 250 mA
- Dimensions: W32 x D40 x H11.5 mm
How to Connect:
Connect the master and slave devices by setting jumper caps for each pattern of power supply and signal voltages on the master and slave sides as shown below.
1) Power: 5V, Signal: 5V → Power: 3.3V, Signal: 3.3V
