2 layer board of 1.07 x 1.87 inches (27.1 x 47.5 mm)
Uploaded: June 13, 2018
Shared: June 14, 2018
Total Price: $9.95

An AVR programmer/tool based on the ATmega32u4. It includes many breakouts for many different functions, including ISP and UART, as well as selectable target power voltage.

BOM:

  • R2,R3: 22 ohm 0805
  • R4,R5,R6,R7,R8: 2.2K ohm 0805
  • C4: 10uF 0805
  • C2: 0.1uF 0805
  • C3: 1uF 0805
  • D1,D5: Red LED 0805 (Marked “Error” and “!” on the board)
  • D2: Blue LED 0805 (Marked “Power”)
  • D3: Yellow LED 0805 (Marked “Prog”)
  • D4: Green LED 0805 (Marked “Ready”)
  • U1: ATMEGA32U4-AU (TQFP)
  • Y1: 16 Mhz Murata resonator
  • SW4: EVQQ2 switch
  • J1: USB_A Molex 48037-0001

All other connectors are 2.54 pitch male pin headers. Jumpers J7, J8, J9 and J10 require pin jumpers like: http://a.co/bSmXWlI to bridge at least two pins for operation.

(ordered, tested, and verified)
