In world where we have Arduino using ATmega microcontrollers with their own IDE one might feel there is no need to directly code ATmega MCUs and take advantage of them in prototyping and rapid development. With this AVR ATmega 16 Development module you can directly connect your DIP package ATmega16 IC without need of soldering in your DIY circuits. It has external power supply module to power up the MCU via DC-005 barrel jack connector. It also has two onboard LEDs one for power indication and other for program run indication. It also has 8MHz crystal onboard which can be replaced with any other crystal to change the clock frequency. You can expand power supply pins upto 4 peripherals with 8 pins onboard for this purpose. It also has standard ISP download interface to program the onboard chip. Specifications 32 I/O pin all the leads. Size:88mmx38mm/3.47\”x1.49\”(inch) Classic ATmega16 minimum system, eliminating the hassle of soldering. Crystal: The socket hole welding facilitate the buyer to replace the crystal, 8M crystal. Power supply: power adapter or external expansion pin power supply (not support ISP download interface power supply) DC-005 Power Block (supporting the transposon is 5.5*2.1mm). Expand outside 4 channel VCC, GND. Reset: Power-on reset and reset button. Power LED (D1) and the program run indicator (D2). Standard ISP download interface. Support chips: ATmega16/ATmega32 and chip which pin-compatible. Product Description Package Contents 1AVR ATmega16 Minimum System Development Module
