MOSI M1 - a Microcontroller module by Siworks

MOSI M1 – Module by Siworks is a microcontroller module intended for engineer, scientists, makers and hobbyists. It can be used as a module in bigger project or as a simple development board. It allows user to create a prototype or a final product quickly and inexpensively, without doing complicated PCB layout.

Hardware

Module is built around ATSAMD21G18 microcontroller with 256 KB of Flash and 32Kb of RAM. Every module has an RGB LED, button, micro SD card connector and of course expansion headers, with 21 GPIOS. Some of them can be mapped as analogue analogue inputs / outputs, PWM outputs, SPI, I2C or UART pins…

Module has USB support for connection to outside world and can also be programmed by it. For more advanced users, there is SWD connector for programming/debugging.

It has support for 128 X 64 OLED I2C display. If you wish to order it, please select it in the side panel.

Module can be purchased in Lite, Medium and Heavy variant (Medium and Heavy available early 2020):

• Lite – Basic module for cost sensitive applications, or applications that don’t really need all the bells and whistled of Medium or Heavy variant.
• Medium – Upgraded Lite variant with sensors and battery charger. Ideal for data logging
• Heavy – Upgraded Medium variant with additional DC/DC converter, which allows it to be connected to power supply up to 36V.

Expansion boards for module well be shortly available. If you are interested in Medium variant, Heavy variant or expansion board, please don’t hesitate to contact us. Module comes fully assembled. If you have purchased OLED module, it comes unmounted.

Variants comaprisson:

Programming

Module can be programmed in Atmel Studio. To ease the development of firmware, developer can use Atmel Start code generator or Siworks provided libraries (currently under development, see GitHub). For more details please see user manual Micro python support is planned in near future.
