The M62 Z80 SBC (Previously the M62-Mini Z80 SBC) is a card that holds the components that constitute a computer.
This design has now been superseded by Revision 2
The card consists of:
- the Z80 CPU
- 16C550 UART interface
- 16K FlashROM
- 16K SRAM
- 4MHz Oscillator
- Reset and NMI buttons
There is a location for a header to allow you to use a FTDI USB-UART cable and here is another header (which mounts on the back of the board) to allow a HC-06 Bluetooth UART module to be attached.
There are 2 sets of jumpers at the top edge of the board, one for the UART base address and one for the ROM/RAM bank selection.
The prototype of the SBC works quite well as is currently my main development platform for creating new software and hardware for the M62.
