The following tables contain components needed to assemble the AVR High Voltage Programmer 2. To simplify the assembly process this project uses through-hole type components.
| Reference designator | Value | Quantity | Notes |
|---|---|---|---|
| R1, R3 | 10KΩ | 2 | 1/8W Resistor |
| R2, R4 | 220Ω | 2 | 1/8W Resistor |
| R5 | 4.7KΩ | 1 | 1/8W Resistor |
| Q1, Q3 | 2SC945 | 2 | |
| Q2, Q4 | 2SA733 | 2 | |
| D1 | 3mm RED LED | 1 | |
| ZIF1 | 10.16mm 28-Pin ZIF Socket or Female Header | 1 | |
| ZIF2 | 15.24mm 40-Pin ZIF Socket or Female Header | 1 | |
| J1 | 1×8 way 2.5mm Pin Header | 1 | Yellow color |
| J2 | 2×6 way 2.5mm Pin Header | 1 | Black color |
| 1×40 way 2.5mm Pin Header | 1 | Black color |
In addition to the above components following parts are needed to test the AVR-HV2 programmer:
For Q1, Q2, Q3 and, Q4, use any matching NPN/PNP transistor pairs. During the prototyping stages, we successfully test this programmer with commonly available general-purpose NPN/PNP transistor pairs such as 2N3904 and 2N3906, BC547 and BC557, etc.
