Gravity-interface expansion shield for FireBeetle boards (29×58 mm), breaking out 10 digital pins, 5 analog inputs, I2C, UART, and SPI via color-coded connectors. Operates at 3.3 V output from a 3.7–5.5 V supply.
One grouped connection is listed in the table but omitted from the graphic until individual pins are available.
| Pin | Type |
|---|---|
| POWER_EN | Control |
| Digital IO (10 pins) | Signal |
| Analog (5 pins) | Signal |
| I2C | Signal |
| UART | UART |
| SPI (incl SSCS options D2-D5) | Signal |
| 3.3V (red pins) | Power |
| GND | Ground |
| VCC input | Power |

Shield
Confirm the data interface matches your host board.
Module pins: 3.3V (red pins), VCC input, GND, Digital I/O (10 pins), Analog (5 pins), I2C, UART, SPI (incl SS/CS options D2-D5). Schematik maps them to your board in the app.
About 270 add-ons across Pi HATs, Arduino shields, and FeatherWings. The same function — motor control, PoE, display — usually ships once per host connector family. Get the host board right first.
