Raspberry Pi Replacement Card

The Raspberry Pi Replacement card let’s you use any HAT or add-on card with any of the following low cost processors: Arduino UNO or NANO, TEENSY, FEATHER or ESP32.

The Raspberry Pi Replacement card has the same form factor with Raspberry Pi and an identical 2×20 pin connector where you can plug any  Raspberry Pi IO card which uses the I2C port for communication. On the opposite side, the card has male or female socket adapters where you can plug the replacement processor.

Since the S-Bridge can accommodate five different families of processors, it comes unassembled.  You will need to solder the 2×20 pin connecting to any Raspberry Pi add-on card, two pull-up resistors  on the I2C lines, and the connectors that fit your target processor.

ASSEMBLY INSTRUCTIONS

In all configurations, the 2×20 pin connector is installed on top, and the processor adaptor connectors on bottom. The 2 pull-up resistors can be installed on either side. Shown bellow is an assembly of the Raspberry Pi Replacement with ARDUINO-UNO.

RASPBERRY Pi Replacement with TEENSY

Solder the R1 and R2 resistors and the 2×20 pin connector. If your TEENSY does not have the pins soldered, you can break two 14 pin sections from the 40 pin male header provided and solder the TEENSY directly on the J2 connector.

If the TEENSY has the pins soldered, break 2 pins from each of the 16 pin female headers provided, and solder the female headers into the J2 connector as shown. Plug the TEENSY into J2 connector.

RASPBERRY Pi Replacement with UNO

Solder the R1 and R2 resistors and the 2×20 pin connector. Break the 40 pin male header provided into 6, 2 x 8, and 10 pins. Solder the breakout pins on the footprint of connector J4 as shown. Plug the UNO into the J4 connectors and secure with standoffs (not provided), if necessary.

RASPBERRY Pi Replacement with ESP32

Solder the R1 and R2 resistors and the 2×20 pin connector. If your ESP32 does not have the pins soldered, you can break two 15 pin sections from the 40 pin male header provided and solder the FEATHER directly on the J3 connector.

If the FEATHER has the pins soldered, break 1 pin from each of the 16 pin female headers provided, and solder the female headers into the J6 connector as shown. Secure the ESP32 processor with stand-offs (not provided) if necessary.

RASPBERRY Pi Replacement with FEATHER

Solder the R1 and R2 resistors and the 2×20 pin connector. If your FEATHER does not have the pins soldered, you can break a 12 pin and a 16 pin sections from the 40 pin male header provided and solder the FEATHER directly on the J3 connector.

If the FEATHER has the pins soldered, break 4 pins from one of the 16 pin female headers provided, and solder the female headers into the J3 connector as shown. Plug the FEATHER into the J3 connector and secure with extra stand-offs (not provided) if necessary.

RASPBERRY Pi Replacement with NANO

Solder the R1 and R2 resistors and the 2×20 pin connector. Cut or pull one end pin of the two 16 pin female headers provided. Solder the female headers on the footprint of connector J5 as shown bellow. Plug the NANO into the J5 connectors.

APPLICATION

The following show one of the easiest and cheapest ways to control AC or DC loads from the Internet. Using the Raspberry Pi replacement card, the ESP32 processor and our  8-RELAY Card, we implemented robust and inexpensive setup which lets you control up to 8 loads of 120V and 8A each from your browser.
