PCB AVR ATMega32
PCB ATMega32 ATMega16 8 Bit AVR Learning
AVR Microcontrollers are one of the most common controllers used in the world. Indeed original Arduino boards were also based upon AVR controllers. Despite availability of 32 bit controllers, the production and sale of 8 bit microcontrollers is still highest. This indicates the usage of these controllers in industry.
This development board has been designed basically to learn AVR controllers. ATMega32 and ATMega16 are two most popular controllers from learning perspective. having a large community and internet support and featuring fairly good memory and peripherals. 
What you learn is easily adaptable to other controllers of AVR Family.

Board Features:
  • On Board 5V Supply to use as standalone product
  • On Board 3.3V regulator to give 3.3V for external circuits
  • Supports ATMega32/ATmega16 Microcontrollers
  • 8 Status LEDs
  • Character LCD (Bothe 8 and 4 bit modes supported)
  • 2 Push switches
  • In Circuit Serial programming (Compatible with USBASP programmer)
  • USART Header, compatible with FTDI232 breakout board to give USB to serial communication
  • All IO Lines available for extension to custom circuits
  • All devices (LCD, LED, Switches) can be connected to pre-defined IO lines using jumpers, or any other IO Line of your choice (100% reconfigurable)
  • Power supply, 5V, 3.3V and Supply Voltage 9V or 12V available through header for external boards
  • Crystal Oscillator Support, you can use any as per your design, we prefer 16MHz crystal.

PCB DAC
PCB 8 Bit R2R DAC
R2R is a technique used to produce any bits of digital to analog conversion. This PCB has been designed to make an 8 Bit R2R ladder along with an OP AMP to produce nice output volts with some driving capacity. The supply voltage of the board should be more than the logic level volts. If using 5V logic levels, then supply voltage should be 6V. or expect a small decrease in the output volts for full 255 number.

PCB JDM In Circuit Programming for PIC
NOTE: Use C828 transistors on place on 2N3906 as labelled on silk screen. JDM programmer is the simplest programmer for microchip PIC Microcontrollers. This PCB works well with almost all commonly used PIC microcontrollers by the hobbyists. It gives out 5V output so should be used with 5V tolerant microcontrollers. A number of client software are available, we prefer using PICPGM which is free to download. JDM programmers work with serial port, and preferably the hardware type RS232 serial port as provided in desktop computers. We have not tested it with USB to RS232 converters.
