Programmer

We have the ATTiny45s in stock, so I want to use the 45-baased programmer in our lab.

Most of these designs seem to have the builtin USB-A connector, but now no computers come with these ports. I’ve also found them very unreliable in the past. SO I want to adapt the board o use a proper USB port (famale is fine, since M-M USB-C to USB-A Mini/Micro)

We have these

PART: H2961CT-ND DESC: CONN RCPT USB2.0 MINI B SMD R/A MFG : Hirose Electric Co Ltd (VA) / UX60A-MB-5ST
COO : INDONESIA ECCN: EAR99 HTSUS: 8536.69.4040 ROHS COMP

PART: 609-4613-1-ND DESC: CONN RCPT USB2.0 MICRO B SMD R/A MFG : Amphenol ICC (FCI) (VA) / 10118192-0001LF
COO : CHINA ECCN: EAR99 HTSUS: 8536.69.4040

The pin pitch on the mini connectors is a little more forgiving than that on the micros, so I will use those.

Pinout is as follows:

1 VCC
2 DATA IN
3 DATA OUT
4 ID (not used)
5 GND
