As part of a group of pcbs I am doing, I am considering adding a new Prop pcb (in addition to my 1"sq CpuBlade)...
  • pcb 1"x0.8" with 0.1" grid around the edges = 32 pins, plus an extra pin on one the inside corner (/RESET)
  • 32-pins are V+(5V or 3V3) & GND, P0-P27, P30, P31
  • P8X32A prop QFP
  • 24LC512 or 24LC64 (64KB or 8KB EEPROM) smt
  • 10K pullup on SDA (P29) only
  • Xtal
  • Bypass caps for overclocking
  • Maybe: 3V3 smt regulator (if available, can be bypassed)
  • Note: P28 & P29 (SCL & SDA) are NOT brought out !!
Is this of interest to anyone (as a tiny prop module - assembled or bare pcb) ???

If so, is the onboard regulator required as an option ???

Price estimate <<US$15 + shipping (unregistered airmail from Australia)

    What! a 32-pin module? Sounds like my PuppyProp P1107 module :) BTW, it's really 32 + the proplink pins and the module is twice as long at 2"x0.75" but it does have microSD and extras.
