Total Price:
$10.75
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:
- R1: 10k ohm 0805
- R2,R3: 22 ohm 0805
- R4,R5,R6,R7,R8: 2.2K ohm 0805
- C1,C4,C5: 10uF 0805
- C2,C3: 0.1uF 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)
- IC1: MIC5225-3.3 SOT-23
- 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.
