With regards to the BOM V1

Should the 10k SIL resistors RP9, RP10 and RP900 Mouser code be 652-4609X-AP1-103LF? It currently has a Mouser code for a normal 10k resistor.

Yeah looks like a mistake.

Gotta be a Windoze thing... Guess I'm a horses as# for today.. :oops: :oops: :oops:

Build the remake without part numbers so should have been able to do the H4 if not for that pesky SMT stuff. :oops: :oops: :oops:

.ods is the default file format for Open Office btw.

Hmm. Found some small error I think in the BOM:

Cap C46, C47 and C48 is listed as 0805 package/SMD, 50pF but mouser part is 80-C315C510F3G5TA. A Thru hole cap. Part of DAC circuit. Must be wrong?

C10 doesn't have a mouser part number. Part of the audio circuit.

Good spot! Will be uploading a updated list later today hopefully.

V3 parts list now uploaded. Various fixes & additions in parts numbers. Added some sockets to the bottom of the list. Added Rapid & farnell for UK people. Prices are for Rapid and farnell, this is really for my own build of boards, so probably no use to outside of UK people.

By the way. Can you use the 32MHz oscillator (2 pin) which I have desoldered from my donor board instead of the XO 4-pin which you have chosen on the mongrel build? The XO have GND, +5V and clock signal. The 2 pin have +5V and clock?

2 pins variants are crystals. They are not the same as 4 & 8 pin oscillators.

If you really want to use 2 pins, your gonna have to build this circuit to go along with it ;)
