Module Features and Description

This module is at a point that we would like to determine interest in this module by means of a pre-order list.

To be put on the Pre-Order list, please send an email with your name, reply email address, country, and quantity you wish to order to pre-order@bsc.powertwig.com and you will be notified when the target quantity is met to start the official pre-order page.

Once we have confirmed enough interest (70 units), a Tindie Fundraiser page will be started to kick the module into production. The module will retail for $35.


The goal was to develop a mini Propeller based module that is compatible to the BASIC Stamp connection pinout and provides full circuit versatitlity to Propeller based projects. It is to provide a method of using a Propeller microcontroller in place of a BASIC stamp with absolute minimal impact to existing PCBs that accept a 24 pin BASIC Stamp module. It is also designed to be used as a core module for building your own Propeller based projects by allowing full access to the Propeller's remaining I/O.

Design Details:

  • Propeller P8X32A-M44 Microcontroller
  • 32KB EEPROM
  • Micro USB for programming as well as direct power input (use your cell phone charger to power your project)
  • 5 Mhz Crystal
  • Vin of 2.5V to 12V supporting automatic step-up to step-down to provide 5V output with up to 2.5A current capability (buck boost switcher)
    • Up to 93% efficiency and greater than 80% efficient under light loads to support battery operation
    • Max 26mV ripple under load
    • Can run down to an input voltage of 1.9v, but requires a minimum of 2.1v to start up.
    • Power options are wide: 2 AA batteries, 3.7v LiPo, coin cells, solar cells, 7.2v NiCAD packs, etc
  • 3.3V available on header with 2A current capacity
    • Max 18mV ripple under load
    • Step down switcher is sourced from 5v output
  • Compatible with 3.3 and 5 volt logic systems:
    • Bi-directional level translators provide 5V I/O on P0-P15 (translators stable to 60MHZ)
    • Prop P16-P31 3.3v I/O accessible
  • 600 Mil, 24 pin, BS2 compatible headers on bottom side
  • Compatible with Parallax BS2 Carrier Boards:
    • USB and Serial Boards of Education
    • BS2 Carrier Board
    • BS2 Super Carrier Board
    • Professional Development Board
  • All Power and IOs accessible from top via 0.050" pitch headers
  • Dimensions: 1.1" W x 1.4" L x 0.55" H
  • Plans for add on boards (breakout, prototyping area, etc)
