The design is based around a PIC18F66K22 microcontroller. The board has a switching power supply supporting an input voltages of up to 34V, five thermocouple channels, HD44780 LCD interface, a battery backed RTC and a microSD card slot.
The control unit interfaces with an electrical system (designed by my colleague) to control solenoid valves, motors and heating elements.
The programming was done in C and there is support for all the hardware except the RTC and microSD card.
