Non-Specific BOM Components

[MrMojoRisinGottaKeepOnRisin]

Sections of the BOM and a Build Image for the Spin FV-1 are somewhat confusing. There is a Build Image showing a 10uH inductor but it's not mentioned anywhere in the BOM. Also, one part simply shows: - crystal for spin FV-1 : 1x Can you provide some part numbers for the inductor and the crystal -or- is there a better BOM out there somewhere?

Thanks!

I've been able to get the eight internal programs on the SPIN FV-1 ROM working just fine but still have not been able to load any custom code into the external EEPROM. It's working as‑is using the PRG button and it can access these eight FX programs

I put the part numbers from your page here for convenience ;)

• (1) 10uH Inductor - Mouser P/N: 810-MLF2012E100JTD25
• (1) Tact Switch Cap - Mouser P/N: 642-1SS00-08.0 (this P/N is blue but is also available in green, grey, white, red or black)
• (1) 32.768KHz Crystal - Mouser P/N: 732-C002RX32.76K-EPB

As for the EEPROM, the programming pins on the board should let you flash it, after i think you should move the jumper to use this external memory. Alternatively you could place the EEPROM chip on a breadboard and flash it externally using an arduino or something

The part number for the button cap you suggested isn't the best option, i think 642-1SS06-15.0 would be better suited (the number after the dash is the height of the cap, 15mm for '-15.0' i think would be more usefull (haven't actually tested or measured this)

I could successfully flash the eeprom using this wiring plan, https://learn.sparkfun.com/tutorials/reading-and-writing-serial-eeproms/all#arduino-hardware-hookup- had to change the address to 0x54 in mxmxmx's code to match the address setting in this wiring (alternatively you could change the wiring to match for 0x50)
