Since somyone really cares about this project, I made it more readable ：）
This board contains:
Motor Drivers: Contains two l298n to drive two 550 motors, each chip allows 2A current, and 550 motor uses up to 3A current, that's why I made this special board to drive them. I fit the most common heatsink just onto these chips, CHECK if it fits your heatsink. They are critical.
EN - This is a digital servo tester using a simple Attiny44 chip.
Code can be downloaded from http://bit.ly/2wBhLwt
(Also need software servo library found here https://playground.arduino.cc/ComponentLib/Servo/ and to program from Arduino need these boards https://github.com/SpenceKonde/ATTinyCore/blob/master/Installation.md)

DCC servo decoder, based on traditional (THT - Through Hole Technology) components, for two switches. Processor is ATMEGA16A-PU. Power is stabilized using a LM2595 buck-down converter. Servo power can be switch-off via MOSFETs. Four relays are available to polarize the frog. Two buttons can be connected to manually change the switch positions. The switch positions can be returned to the command st...
This PCB is a simple Arduino Nano based Laser Cannon! We here at ACBR ship our Robotic Laser Cannon Kits with an RF Nano (Arduino Nano with built-in NRF24L01), so the laser cannon can be controlled using the onboard joystick, or through the integrated radio chip. Either way, it's a ton of fun. We have these available as full kits with everything you need in our shop online, but we wanted to post...
This board utilize an ATTINY85 chip to control a servo motor using Serial Command, featuring a MOSFET for switching on/off the servo motor, an AMS1117 3.3 regulator to provide power for the ATTINY85chip and a status LED. Program not included. You have to use Software Serial on Port 3 and 4.
Recommend Serial Command: M-Command
This schematic uses two LDRs (Light dependent resistor) to sense the light and a servo motor to automatically rotate the solar panel in the direction of the sun light. The Arduino code is available on [Arduino Solar Tracker using LDR and Servo Motor]
