Rpi level shifter v1
About the Rpi level shifter v1 PCB
Rpi level shifter v1 is an open source PCB design by charkster, published on GitHub under the MIT license. It is a 2-layer board measuring 51.3 × 20.3 mm, with 18 components from 10 distinct parts.
Other key parts include the NVT2010PW, AP2112K-1.8 and AP2112K-1.2. By type, the board carries 6 resistors, 4 ICs, 4 connectors and 4 capacitors.
From the project
rpi_level_shifter_v1
This board is designed to not fit over-top the RPi board, but rather over the side.
Each board needs to have the top-left pin of J1 connected to the 3.3V RPi header pin. One board can service the I2C and UART pins (along with a couple of GPIO) and another board can service SPI pins. BCM GPIO's 13, 16, 19, 20, 21 and 26 are not accessable with this board.
The J3 connector must only have one horizontal jumper!! Either HVEN or LVEN, or damage to the RPi pins may occur (you have been warned). Additionally, the J4 connector must only have one horizontal jumper!! The RPI5V is only available if…
