KSh 180.00
4-channel bi-directional logic level shifter for safely connecting 3.3V and 5V devices over I2C, UART or SPI.
In stock
This 4-channel bi-directional level shifter lets 3.3V and 5V devices talk to each other safely. Each channel works in both directions, so it handles I2C as well as SPI, UART and GPIO signals.
Key features
- 4 independent bi-directional channels
- Safe for I2C (open-drain) lines
- Separate LV and HV supply pins
- Small breadboard-friendly board
Specifications
| Channels | 4 |
|---|---|
| Low side (LV) | 1.8V-3.3V (typical) |
| High side (HV) | 5V |
| Design | MOSFET-based, BSS138 (typical) |
Typical uses
- Connecting 3.3V ESP32 or Raspberry Pi to 5V sensors
- I2C, UART and SPI level translation
- Mixed-voltage prototypes
Tip: Connect LV to the lower voltage, HV to the higher voltage, and GND to both systems.
Buying in Kenya: Available from Bluepack Nova with delivery anywhere in Kenya.
