We have made several updates to the component layout, adding a second set of pins on the opposite side to the 40 pin connector. This distance is an integer alignment of  2.54mm pitch, making it easy to use for extended prototyping.

The entry power routing has been revamped with options for solder bridging the 3v3 supply. The three pin USB/JST selection is how through hole.

cAno2 is based on the excellent MSP430FR5994. Designed for long term data collection in the big outdoors, it has BLE to allow easy configuration. An outline specification listing can be found below. Check out the original post here.

In a small footprint it integrates all the major functions you may need for your data set.

    • GPS
    • 9DOF(Accel/Magneto/Gyro)
    • Temperature/Pressure/Humidity
    • UART, SPI & I2C breakout
    • SD Storage
    • 3.7-17Vin
    • BLE
4xUART (BLE, XBee,GPS,Header)
1xSPI(SD)   (SD socket on rear)
2xSPI/I2C(Header,Header)  Can be configured as I2C master or slave
BLE (external power switch)  RN4871 Jumper UART connection for direct access to MSP BSL or UART. Alternatively for BLE access from an external USB2UART.
GPS (option) (external power switch)  Firefly X1 (optional battery backup, BR1225, CR1216, CR1220, CR1225)
XBee (option) (external power switch)  SMD & Through hole connector (on rear)
9DOF (Accel/Magneto/Gyro) (option)  MPU-9250 (shared power switch*)
Temp/Pressure/Humidity (option) BMP280 (shared power switch*)
Magnetic SM351RT
1xBlue LED
1xRedGreen LED
3v7-17V input Buck  3v3 Out (fuse protected input)
 3V-3v6 Vin for MSP  Main power input for board
 USB Micro for 5V input & LiIon charge  (on rear)
 LiIon JST connector  (on rear)
 LiIon charger
 40 Pin connector 2xSPI, 1xUART, 3v3, 3v7-17V, GPIO
 8 Pin connector 1xUART (XBee), GPSVBasckup, 3xGPIO(A3-5)

Specification, user guides and development resources for all modules can be found at the links above.


No onboard programming is available, cAno2 can be programmed and debugged using the MSP430FR5994 Launchpad available here. This also provides a USB UART interface, accessed via the 40-pin or BLE headers.

With LoRaWan shield.
