About the Bluetooth nes advantage PCB

Bluetooth nes advantage is an open source ESP32 PCB design by cajunpanda, published on GitHub under the MIT license. It is a 2-layer board measuring 78 × 36 mm, with 36 components from 20 distinct parts.

Its main chip is the ESP32-WROOM-32E-N4, from the ESP32 family. Other key parts include the TP4056-42-ESOP8 and TPS63900DSKR. By type, the board carries 13 resistors, 10 capacitors, 4 diodes, 3 ICs, 3 connectors and 2 transistors.

It belongs with the iot & wireless, retro computing and power & battery designs in this gallery.

From the project

A bluetooth mod for the NES Advantage classic controller.

Open hardware for the Bluetooth NES Advantage.

The full build reference (architecture, BOM, pin and connection maps, power path, assembly, and layout notes) is in ../docs/HARDWARE.md. Pin assignments match the firmware (../firmware/main/boardconfig.h`).

- MCU: bare ESP32-WROOM-32E-N4 on a single 3.3 V rail (the Advantage's logic runs at 3.3 V, so there is no 5 V rail and no level shifting). - Power: barrel jack (+5 V) to TP4056 charger, 1S LiPo, discrete load-share power path, TPS63900 buck-boost to 3.3 V. NES LATCH/CLK/DATA sit on RTC-capable GPIOs so the ULP polls the shift registers in…

Bluetooth nes advantage: common questions

What microcontroller does the Bluetooth nes advantage use?

The Bluetooth nes advantage is built around the ESP32-WROOM-32E-N4, from the ESP32 family.

How big is the Bluetooth nes advantage PCB?

The Bluetooth nes advantage measures 78 × 36 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bluetooth nes advantage?

36 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bluetooth nes advantage design files?

From the cajunpanda/bluetooth-nes-advantage repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Bluetooth nes advantage design in my own project?

Yes, under the terms of its MIT license, which cajunpanda chose for the repository.

Can I test firmware for the Bluetooth nes advantage 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.
