NEWLatest V4 revision: the newest and best QuinLED Dig-Uno yet
V4 is a completely reworked board with a new DC-DC converter that fixes the 24V issue found on earlier revisions. Here's what's new compared to V3:
- Completely reworked board — V4 revision 1, pre-assembled release 2026-10-31
- New DC-DC converter design — Fixes the 24V issue; the board remains 5V-24V
- New relay port and circuit — Uses a load-switch (still 5V trigger out, shared with Q1), smaller port with included pigtail cable
- Improved level-shifter circuit — Extra hardware ESD protection, shared resistor-switcher switches
- New I2C port — Stemma QT / JST SH 1.0mm
- Single-board Ethernet — Ethernet board lip points up, no longer a stacked board
- Onboard digital PDM microphone — Included on the ESP32, so every Dig-Uno V4 has a built-in mic
- New GPIO layout — New ESP32 module uses different GPIO pins, see the pinout guide
