ESP32 Interface
About the ESP32 Interface PCB
ESP32 Interface is an open source PCB design by dennowiggle, published on GitHub under the LGPL-2.1 license. It is a 4-layer board measuring 100 × 79 mm, with 59 components from 8 distinct parts.
Other key parts include the SN74LVC1G04DBVR, SN74LVC1G125DBVR and SN74LVC8T245DBR. By type, the board carries 28 capacitors, 24 resistors and 7 ICs.
It belongs with the retro computing and usb & debug tools designs in this gallery.
From the project
Facilitate learning the Z80 Retro! hardware and software.
1. The 'output' directory contains the BOM, netlist, and PDF schematic.
3. Silkscreen box on back side should extend around R501.
4. Holes for U505, the ESP32 module, are tight but it is possible to fit the module in. Larger pin holes would be preferred.
