About the Adc PCB
Adc is an open source PCB design by dimitrit, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 81 × 36 mm, with 5 components from 5 distinct parts.
Other key parts include the AD7819. By type, the board carries 2 connectors, 2 capacitors and 1 IC.
It belongs with the retro computing designs in this gallery.
From the project
A range of gadgets that can be plugged in to the PAL-1 RIOT Expansion Module to provide specific functionality.
The PAL1-ADC is an Analog-to-Digital Converter for the PAL-1 system intended to plug in to the PAL-1 RIOT Expansion Module[^1].
The analog-to-digital converter enables high throughput data capture (up to 200 kSPS) via an 8-bit 'bus'. A small on-board prototype area facilitates experimentation. Refer to the AD7819 datasheet[^2] for details.
The wozfp.a65 and bcdfp.a65 source files are from Jeff Tranter's github repository and have been modified for vasm6502oldstyle` syntax.[^3]
