During the month of May, DonTronics designed and produced 3 new PIC based prototyping boards for the SimmStick(tm) platform and these boards are shipping right now. All I/O boards also suit the Atmel.001 (AT89C2051) SimmStick(tm) from SiStudios. They should suit any future micro migration to the SimmStick building block. These are: DT003: Simmstick 4 slot mini-bus, power supply, and comms port with D-9 and Max-232. DT101: A PicStic(tm) equivalent circuit on a SimmStick(tm) platform. PicStic(tm) versions 1, 2, and 3, all rolled up into one, plus a Max-232 and 24LCxx type EEprom. 1" module. DT203: 24 LEDs, 4/8 switches on a SimmStick platform. 2" module. Uses 1 to 3 ULN2803's, 4 momentary switches, 8 link selected switches. During the month of June, these will be released: DT204: Expansion board for SimmStick Bus. 2" Module. 1) Can be used just to add 4 slots to a bus. The bus continues through. 2) Used as a right angle or left angle bus connection, so that you can have a SimmStick facing up or down, or both. 3) Signal Isolation and cross connection using either links or DIP switches. 4) Convert Simm connector to 30 pin Female. DT205: Relay board for 4 relays. Carries a partial bus on to the next module so that a total of 16 relays could be used by cascading four boards. Uses SimmStick bus signals D0 to D15. Can select a group of 4 bits by placement of a single ULN2803 (or 2003) in one of four positions. 4 monitor LEDs. Screw terminals for outputs. Suits many Relay types. This is a 2.5 Inch board.
