About the Twisted-Listen-Rev2 PCB

Twisted-Listen-Rev2 is an open source PCB design by Triax-Labs, published on GitHub under the CC-BY-NC-4.0 license. It is a 4-layer board measuring 14 × 32.7 mm, with 54 components from 20 distinct parts.

Other key parts include the LPA2103AQVF, TCA9536DTMR, LP5910-1.8DRVR, ES8316 and KH-1.27FH-2X10P-H4.3-SMT. By type, the board carries 28 capacitors, 11 resistors, 5 ICs, 4 test points, 2 inductors and 1 connector.

It belongs with the audio, displays & leds and sensors designs in this gallery.

From the project

The key chain sized ESP32-S3 expandable platform.

Twisted is a tiny (14x32mm to be precise) ESP32-S3 based platform, which has dual Xtensa LX7 cores, 4Mb of flash, 2Mb of PSRAM, 512Kb of SRAM as well as BLE and WiFi on board, paired with an 0.42" IPS LCD, a keypad, a Neopixel and built-in battery management with USB OTG.

There is one more thing, the platform is extendable! It features a 20pin 1.27mm expansion header which allows you of attaching other boards that add more feature, and also give the Twisted a reason for its name.
