Finally, a UART adapter I don't have to apologise for leaving on the bench. Build quality is excellent, and the FTDI drivers just work.

Built for the bench
The DG-UART is a USB-C serial adapter for people who care what's on their bench. FTDI inside, full ESD protection on every signal line, and a hardware voltage switch — slide on the Board, rotary on the Cased — that handles 1.8V, 3.3V, and 5V without jumpers, software, or apology.
Built around the FT232RL
We chose the FTDI FT232RL because driver support is mature across Windows, macOS, and Linux — you plug it in and it works. No chasing down CH340 drivers, no wondering whether the latest macOS update has broken anything. It's the bridge chip you already trust, wired up properly.
Up to 3 Mbaud. Whether you're dumping serial output from an ESP32, flashing an RP2040, or consoling into a network switch — it keeps up.
Three voltages, one switch
The Board has a slide switch on the top edge. The Cased has a three-position rotary. Either way — flick to the voltage your target expects and go. No jumper blocks, no solder bridges, no accidentally driving 5V into a 1.8V target and watching the magic smoke escape.
ESD protection where it matters
Every signal line is protected by a Texas Instruments TPD4E001DRLR ESD array — IEC 61000-4-2 rated, sitting between the header and the FTDI chip. If you've ever killed an adapter by touching a probe at the wrong moment, you know why.
UKCA and CE marked.
Common questions
Yes. The FT232RL uses standard FTDI VCP drivers — built into macOS and Linux, auto-installed via Windows Update on Windows 10 and 11. You plug it in and it works. No DG-specific software, no signup, no installer to hunt down.
The electronics are identical — same FT232RL, same ESD protection, same pinout, same performance. The Board is a bare PCB: lighter, thinner, and £24 less. The Cased version wraps the same board in a bead-blasted, anodised aluminium enclosure. Pick whichever suits your bench.
No. The DG-UART is a signal-level adapter, not a power supply. Your target needs its own power source. Trying to draw power from the adapter can damage both devices.
Yes — anything with a UART. ESP32, RP2040, STM32, ATmega, Raspberry Pi, network switches, GPS modules. If it speaks serial, the DG-UART will talk to it.
Standard rates from 300 baud up to 3 Mbaud. The most common embedded default is 115200 8N1, which is where most people start.
Probably not. macOS and Linux include FTDI support out of the box. Windows 10 and 11 install the driver automatically over Windows Update. If something goes wrong, grab the official VCP installer from ftdichip.com — but most people never need to.

Multi-voltage support without jumpers is a revelation. I switch between 3.3V and 1.8V targets daily and this handles it beautifully.
★★★★☆
Bought the board for the lab, then the cased version for myself. The aluminium enclosure is properly premium.
