A tiny Propeller Development Board
The P8XBlade2 is the first member in my latest family of tiny Propeller Based Microprocessor boards.
- PCB 0.78"x1.28" (19.8x32.5mm) 1.0mm thick Blue ENIG (gold finish)
- P8X32A Parallax Propeller Microprocessor
- 12MHz crystal (96MHz clock frequency)
- EEPROM 64KB (preprogrammed) with WE link
- microSD socket (preprogrammed microSD card optional extra) on pins P12..P15
- All 32 I/O pins, Reset, 5Vin, 3V3 out and Gnd brought out to 0.1" pitch pads
- Onboard 3V3 voltage regulator
- Onboard (linkable) transistor reset circuit
- Onboard series resistors (linkable 0/68R/136R) and 3V6 zener diode protection on both P30 & P31 lines
- Requires 5VDC Regulated power
- Able to use (optional) cheap USB-Serial CP2102 6-pin (~US$1.25) connection to PC (does not require PropPlug)
- Optional (free) my Prop OS (propeller operating system)
The P8XBlade2 can be used as the basis of any Propeller Development System.
Together with a microSD card formatted with FAT16/32 and loaded with my free Prop OS (Propeller Operating System with similar commands to the old PC DOS and CPM), the Prop will boot into the OS, or run a user program. Programs can be copied directly to the microSD card on your PC/laptop, or you can use an (optional) USB-Serial converter or PropPlug to download your program directly to the Propeller or EEPROM (requires WE link enabled).
You can use an (optional) USB-Serial CP2102 6pin converter (~$1.25) instead of a PropPlug to download programs to the Propeller/EEPROM because the required transistor reset circuit is built on the P8XBlade2.
