Sometimes you want a dev board you can take anywhere and test out an idea at the drop of a hat. The Ultimat3 dev board aims to do just that by cramming a microcontroller on a PCB along with a 9-axis gyro sensor, a Temperature/Pressure/Humidity Sensor, an OLED display, a micro SD card slot and a LiPo charging circuit. That’s quite a bit of hardware to jam into such a small space which really puts this dev board in a league of its own.
The microcontroller used is the SAMD21G18A ARM Cortex M0+ which is compatible with the Arduino IDE since the Arduino Zero board also uses it as its processor. The gyro sensor is the MPU6050 and the Temp/Pressure/Humidity sensor is the BME280 which are both pretty familiar chips that have plenty of libraries out there especially for the Arduino platform.
With the full colour OLED display you can do all kinds of graphing or gaming or whatever else you can think of. The micro SD card slot can be used to easily log values from any of the onboard sensors. The LiPo charging circuit lets you charge a small LiPo battery using the programming header and of course run the board on battery power which is a nice little extra feature of this board.
