Stereo Balanced Audio Front-End for Daisy Seed 2 DFM Platform

Modular 3.3V Arduino Nano ESP32 controller with I2C-connected Modulino Buttons and LED Pixels nodes plus Qwiic JST-SH daisy-chain connector.

It is a daisy seed template with pinout on a board #daisy #seed #template #iot

Compact ARM Cortex STM32 music synth controller modeled after Daisy Seed, with external PSRAM, PCM3060 audio codec, three potentiometers, eight LEDs with resistors, two buttons, audio jack, rounded-rectangle PCB, mounting holes, and row-aligned controls.

Three-stage stereo DSP effects processor using three Electrosmith Daisy Seed modules, shared 9V-to-5V power, panel controls, USB MIDI, and internal stereo audio chaining.

Carrier PCB for a 38-pin NodeMCU ESP-32S controlling a 24 V industrial RGB stack light over I2C, with 24 V power input, daisy-chain terminals, 24 V-to-5 V regulation, and jumper-selectable external/onboard opto output drivers.

Arduino Nano-based DCS-BIOS RS-485 interface module using a MAX487CPA+ transceiver and two RJ45 sockets for bus daisy-chaining.

CMU board for a 32S3P battery sub-module in a 192S3P system, using ADBMS6830 multicell AFE ICs daisy-chained by isoSPI to a single S32K344 MCU.

Five WS2812B-3535-style addressable RGB LEDs in a daisy-chain row with per-LED 100nF decoupling, a 330Ω data input resistor, and external 5V/GND/DATA pads.

A NES fight stick/arcade button breakout board with uni-tap NES controller passthrough. The passthrough NES input will merge button presses with the boards, enabling gamers to daisy-chain controllers into one singular output. This is useful for both building arcade style fight sticks as well as accessibility devices.
