This development board is intended to facilitate prototyping and development
of projects and products based on the ZX-1281. In addition to the ZX-1281
microcontroller, the board contains an RS-232 serial port for downloading
programs and a USB-serial converter that can alternately be used downloading.
The board also contains a RAM chip and interface that can be enabled optionally
to provide a full complement of 63K bytes of User RAM.
The board, which measures 3.7 x 5 inches, can be powered from the USB hub or from the on-board regulator
(requires an external "wall wart" power supply, 8-15VDC). SIP sockets
(included but not shown) can be installed in the board to simplify making
connections from Ports A-G to your external circuitry.
Documentation for the ZX-1281 Development Board may be found at http://www.zbasic.net/doc/ZX-1281_DevBoard, also available in PDF form. The documentation for the earlier Rev. 2 board is available in PDF form.
