Its main chip is the ESP32-S3-WROOM-1-N8R2, from the ESP32 family. Other key parts include the LFE5U-25F-7TG144C, TLV1117LV25DCYR, TPS3808EG33DBVR, 74AHC1G09GW,125 and W25Q128JVSIQ. By type, the board carries 174 resistors, 123 capacitors, 17 diodes, 15 transistors, 15 inductors and 13 ICs.

It belongs with the usb & debug tools, iot & wireless and retro computing designs in this gallery.

From the project

3.3V Retro computer project => FPGA + RCBUS + CPU boards making a custom system.

The PETER board provides video, audio, I2C, SPI, SNES controller, 2x USB UART, and PS2 keyboard and mouse connection to a 3.3V RCBUS card slot and expansion connector.

In addition there is an ESP32-S3 WiFi module for programming the FPGA and system bootloader(s), Zilog ZDI, WiFi console and additonal features. There are on-board connectors for provision of a W5500 Wizmon Ethernet module and DS3132 Real Time Clock + AT24C32 EEPROM module.

PETER: common questions

What microcontroller does the PETER use?

The PETER is built around the ESP32-S3-WROOM-1-N8R2, from the ESP32 family.

How big is the PETER PCB?

The PETER measures 180 × 110 mm, has 4 copper layers and is 1.60484 mm thick.

How many components are on the PETER?

371 components, from 36 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the PETER design files?

From the dennowiggle/Retro-PETER repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the PETER design in my own project?

Yes, under the terms of its LGPL-2.1 license, which dennowiggle chose for the repository.

Can I test firmware for the PETER without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
