About the 1802-Mini-1854-Serial PCB
1802-Mini-1854-Serial is an open source PCB design by dmadole, published on GitHub. It is a 2-layer board measuring 100 × 100 mm, with 44 components from 33 distinct parts.
Other key parts include the CDP1854, 4049, 74LS174, 4019 and 4051. By type, the board carries 12 jumpers, 11 ICs, 8 connectors, 8 capacitors, 2 diodes and 2 resistors.
From the project
Sixteen baud rates from 300 to 57600 Jumpers to determine default baud rate at reset Baud rate can be changed by software No rare chips except the CDP1854 itself Supports group I/O port expansion Jumper-selected address 2/3, 4/5, or 6/7 Jumper-selected interrupt poll bit on EF1-E
