IMPR-DISP-01
Gives a RAD-01 Rev2 node its own screen and controls, on a standard I²C interface you can use in your own designs.
Mesh status at a glance
A plug-in module for RAD-01 Rev2's top port. The screen shows which radios are up, who is in reach and whether anything needs attention; four buttons, a buzzer and status LEDs let operators work the node without a phone.
Designed and built in-house: PCB, display firmware and mechanical fit.
Screen, controls and sensing on one board
- 01 A 0.96-inch 128×64 OLED with its own reset line.
- 02 An I/O expander drives four buttons, a buzzer and three status LEDs over one I²C bus.
- 03 An ambient light sensor on the same bus.
- 04 A 20-pin DF12 connector on the underside: I²C, SPI lanes, 3.3 V and reset.

Mesh health in one glance.
We built DISP-01 so an operator can read a node’s state without a phone or a laptop. The same idea works on any connected product.

How we use it
- See at a glance which radios are up: LoRa, Bluetooth, Wi-Fi and ESP-NOW.
- Peers and relays in reach, so a node in a dead spot is obvious.
- Uptime and restarts, so a struggling node stands out.
- A footer that flips into a warning bar, readable from across the room.
On your IoT product
- Show your device’s own state: sensor readings, link status, battery and alerts.
- Use the four buttons for local menus and on-site configuration.
- An 80 dB buzzer and status LEDs for alarms and siren-style alerts people notice without looking at the screen.
- Ambient light sensing, for example to adapt brightness indoors and out.
Made for IMPR-RAD. Open to your design.
In the IMPR-RAD ecosystem
DISP-01 is designed for the top port of RAD-01 Rev2. It plugs in at any time, and our mesh firmware drives it out of the box.

On your own hardware
The mezzanine uses standard buses, so DISP-01 isn’t locked to our radios. We share the pinout with customers building custom applications on other boards and microcontrollers.
