Learn About:

The MOTHERBOARD is an Arduino™ compatible microcontroller breakout board designed around the ATMega328P. The board comes in a solder-it-yourself kit with all the components you need to build the circuit, together with wire and stand-offs so you can stack it together with our other kits. It also comes with an online manual that will help you understand the circuit, why and how it works, as well as a glossary of components to help you troubleshoot and fix any electronics!

Arduino IDE Compatible
On Board RTC (Real Time Clock) + Battery Backup
Powered through USB Micro or Overvoltage Protected Terminal Blocks
All Through-Hole Components (except USB Micro Socket)
Through Hole Test Points on every IC pin
FTDI Header for easy programming
Bluetooth Header
Power-On LED, D13 LED
Optional Surface-Mount LED for every IO Pin
Designed to be easy to follow and understand
40+ page manual with every part of the circuit and every component explained in an easy to follow way

Required Tools:

Uses the well documented and supported ATMega328P Microcontroller
On-board Real Time Clock with time and date, battery backup, and alarm
18 IO pins, accessible through terminal blocks for secure connections
6 of these are Analog (10-BIt) pins that can read inputs from 0V to 5V (Vcc) via the ADC (Analog to Digital Converter)
12 are Digital pins, these read and write on or off
6 of the Digital pins support PWM (Pulse Width Modulation), which can be used to dim LED’s or control the direction of a servo by modulating the pin at high frequencies
Each IO pin has space for a 0603 (surface mount) resistor and LED. Great for keeping track of what your IO pins are doing while learning to code. (can be disconnected via jumper if installed)
Digital Pin 13 has a through hole LED for all your blink sketch needs. (can also be disconnected via jumper)
The board runs on 5V which can be supplied through the USB socket or the Vin terminal. (USB limited to 500mA)
The Vin terminal has overvoltage, and overcurrent protection, to protect the circuit if you connect more than 5V, or if you accidently reverse the polarity.
Vout connects other boards to the MOTHERBOARDS VCC
Programmable through an FTDI USB board, or using an Arduino with a DIP28 socket
Bluetooth header can be used with most popular HC06 or similar Bluetooth modules
Height and Width: 100mm x 100mm
Stacks/Panels with other Short Circuit Boards
Clearly printed traces to aid understanding of the circuit and to help with fault finding
Back of board is printed with the circuit so you can see every trace, even when the components are soldered on. This makes it easier to understand and to fault find
