Vesper bill of materials
Since I already got a few mails about how much it would cost to make one of my Vesper boards, I have put a list together of the parts needed for it.
|3||Terminal blocks 2 pole|
|1||SD card connector|
|1||Voltage regulator (MCP1702T-3302E/MB)|
|4||10kΩ resistors||R1, R2, R3, R10|
|3||1kΩ resistors||R7, R8, R9|
|2||1uF capacitors||C2, C3|
|1||100pF (0.1nF) capacitor||C1|
|1||Atmel EEPROM CryptAuthEE SHA256 1Wire|
|2||1N4148 diodes||D1, D2|
|2||2N3904 NPN Transistor||Q1, Q2|
|1||2 layer PCB|
Adding to this there are the shipping, but since the parts can be found at various places I am going to just leave it out. Adding what I had to pay in shipping from mouser, also bumped it up by quite a lot.
Another thing to notice is, this is the price for the component of 1 board. Many components are purchased 100 pieces, or more at a time.
