satshakit born during my FabAcademy2015 as one the first test boards for my quadcopter final project. As some of my fellow students had difficulties with Fabkit, they tried to make this prototype board. The board was very appreciated that now almost all my fellow students made it for their exercises, or use it as a starting point for their final projects. Thus I decided to do this release, if anyone wants to try it. Now, one year later, I am again in a FabLab developing new satshakit boards in my spare time.
satshakit is a 100% Arduino IDE and libraries compatible, fabbable and open source board, and also an improved version of Fabkit.
Main improvements and features over Fabkit are:
- 16Mhz instead of 8Mhz
- crystal instead of resonator
- costs less (7-9 euro vs 13 euro)
- 100% compatible with default Arduino IDE (satshakit is recognized as Arduino UNO)
- ADC6/7 connected instead of ADC6/7 not connected (satshakit laser and cnc)
- larger space to easy soldering (satshakit laser and cnc)

satshakit laser and satshakit cnc are the standard versions of the satshakit. They are actually the same board, showing some layout differences to improve the fabrication process using a fiber laser cutter machine, or a little cnc mill. These satshakits are meant to be a general purpose board, having the full Arduino pinout plus ADC6/7 pins, large space for easy soldering and two led onboard for power and pin 13.
Here is the satshakit laser board:

Due to the power requirements of a multicore satshakit system and to eventually provide power to 3.3V devices, I have also developed a simple power board. This power board can work with 7V-12V as input voltage, and give out 5V and 3.3V. I made this power board with the components I had available, obviously you can make this board only with SMD components.

Here is a picture of a soldered power board:
A satshakit board is totally like an Arduino board, thus is possible to use the Arduino IDE without any modification. When you finish solder satshakit, you're ready to program it. If you want to use satshakit as an Arduino, you first need to upload Arduino bootloader. This will also set the ATmega328P fuses as the same of an Arduino UNO. To do this you need to use a programmer, for example another Arduino or FabISP. If you plan to program a satshakit with an Arduino, be sure to upload the Arduino as ISP skecth before connecting the satshakit to it.
Here are the connection schemas to program satshakit laser or satshakit cnc with an Arduino as ISP or with a FabISP:
Once everything is connected, follow these steps to upload Arduino bootloader:
- open Arduino IDE
- select proper programmer (for example Arduino as ISP or USBtinyISP)
- select Arduino UNO as board
- click on tools->Burn Bootloader
With a satshakit cnc or satshakit laser you can use an FTDI USB cable to upload and use you favourite sketch without the need to use a programmer anymore.
Here is the connection schema to program a satshakit using the FTDI cable:
Remember that if you don't have an FTDI cable you always need a programmer, and to select File->Upload using a programmer to upload the code to satshakit.
To use a satshakit like an Arduino, here is the Arduino pinout on satshakit cnc or satshakit laser:
