# CM5_MINIMA_REV1

_Compact, feature-filled, CM5 LoRaWAN carrier board_

## **OSHWA**:

This project is certified as open-source hardware under the UID: IT000019

https://certification.oshwa.org/it000019.html

## **Warning**:

Board tested, everything works, except for the RAK3172 UART, which was moved from UART0_IR to UART2. It works with this change, schematics, layout and production files are corrected.

_Proceed at your own risk._

 [PDF SCHEMATICS](https://github.com/piecol/CM5_MINIMA_REV1/blob/main/CM5_MINIMA.pdf)

 

## **Peripherals**:

- USB-C PD (CM5 can negotiate power delivery!)

- USB2.0 

- Gigabit Ethernet with cutout magjack for low profile

- HDMI port

- RAK3172 lorawan chip from RAKwireless

- SHTC3 Sensirion temperature and humidity sensor

- I2C connector (3V3 only)

- Fan connector

- Various status LEDs

- Compact size 5.4 x 5.7 cm

## **Stackup**:

4L (SIG:PWR | GND | GND | SIG:PWR)
