NanoPi Zero2 Hardware Build
This guide covers assembling a FriendlyElec NanoPi Zero2 into a small, low-cost dedicated Orb sensor. Once the hardware is assembled, build and flash an image for it with Sensorbox.
Why the NanoPi Zero2
The NanoPi Zero2 is a compact single-board computer that makes a capable always-on sensor:
- 1 GbE Ethernet
- M.2 Key E slot for an internal Wi-Fi card
- USB-C OTG
- Very small footprint
Bill of materials
| Item |
|---|
| Device + case (includes shipping) |
| 64 GB eMMC (optional) |
| Wi-Fi 7 upgrade (optional): |
| Intel BE200 |
| 6 GHz antennas |
| 0.5 mm thermal pad |
The eMMC and Wi-Fi 7 upgrade are both optional. A basic build that relies on Ethernet or the stock wireless costs considerably less.
Optional: Wi-Fi 7 upgrade
If you want Wi-Fi 7, you'll install an Intel BE200 card in the M.2 Key E slot. The stock antennas do not reliably support 6 GHz, so you'll also need new antennas. These have been tested and work: Leankon dipole flex Wi-Fi 6E antennas.
A 0.5 mm thermal pad on the BE200 is required — don't skip it. The card needs the pad to transfer heat to the case and run reliably.
Steps
- Remove the stock antennas.
- Install the new 6 GHz antennas in the same locations.
- Install the Intel BE200 card in the M.2 Key E slot.
- Add the 0.5 mm thermal pad to the BE200.
- Route the antenna wires and attach them to the BE200.
- Close the case.
Build the sensor image
With the hardware assembled, follow the Sensorbox guide to build and flash an OpenWrt-based Orb sensor image for the NanoPi Zero2. Select the NanoPi Zero2 in the configurator, provide your Wi-Fi credentials, and flash the resulting image to your SD card or eMMC.
