PiGear Nano is an Nano-ITX carrier board for Raspberry Pi CM4 (Compute Module 4) designed for industrial applications with a -30°C to +80°C temperature range, 7 to 30V DC input, as well as RS232, RS485, and CAN bus interfaces.
The board also features one Gigabit Ethernet port, one HDMI port, MIPI DSI and CSI display & camera interface, M.2 SSD storage, eight USB 3.0 ports, mini PCIe and SIM card sockets for 4G LTE cellular connectivity, and various digital input and output interfaces.
Pigear Nano specifications:
- Supported SoM – Raspberry Pi CM4 and CM4 Lite modules
- Storage – 1x NVMe SSD M.2 socket, 1x MicroSD card slot for Compute Module 4 Lite only
- Display I/F – 1x HDMI Type-A connector, 1x MIPI DSI interface x 1
- Camera I/F – 1x MIPI CSI interface
- Networking
- 1x Gigabit Ethernet RJ45 port
- Optional 4G LTE/GPRS via mini PCIe socket plus SIM card slot
- USB – 8x USB 3.0 Type-A connector, 1x USB 2.0 Type-C connector for flashing CM4 or powering the board
- Serial – 2x RS232, 2x RS485, 1x CAN bus, one-wire via terminal blocks
- Expansion via terminal blocks:
- 4x 18-bit ADC inputs
- 4x Digital inputs
- 4x Digital outputs
- 4x configurable digital I/O’s
- Misc
- Real-time clock supper capacitor for off-power timekeeping
- Buzzer
- Power and user-programmable LED
- 5V fan interface (PH2.0 connector)
- Power and Reset buttons with one extension connector each
- Power Supply
- DC 7V~30V via 2-pin terminal block with reverse polarity protection
- DC 5V via USB Type-C connector
- Quiescent Current ~1mA
- DImensions – 12 x 12 cm (NANO-ITX form factor)
- Weight – 150 grams
- Temperature Range – -30°C to 80°C
- Humidity – 0 to 80% RH, no condensing
In case you wonder how the USB 3.0 ports are connected to the system-on-module, this is explained in the user manual:
PiGear Nano extends 4 channels of USB3.0 interfaces from the PCIE on Raspberry Pi Compute Module 4, and then extends a PCIEx2 for NVME SSD, a Mini PCIE for 4G LTE module, and also 8 USB 3.0 ports.
That means a PCIe to 4x USB 3.0 chip, two of which connected to two USB 3.0 hubs to bring out the 8 USB 3.0 ports, one to the mini PCIe socket, and the final USB 3.0 port connected to a USB to PCIe chip for the NVMe SSD…
That’s not ideal, but this setup is due to the limitation of the Broadcom BCM2711 processor found in the Raspberry Pi module, and a processor such as Rockchip RK3568 would really shine in this type of board.
I understand PiGear Nano is designed to run Raspberry Pi OS which you’d need to install on the eMMC flash or a MicroSD card (CM4 Lite), and then download and install a script to support all features of the board:

1 2 |
wget https://www.uugear.com/repo/PiGearNano/installPiGearNano.sh sudo ./installPiGearNano.sh |
This script makes changes to config.txt file, creates pgnano directory for PiGearNano’s RTC and IO configuration script, and installs UWI (UUGear Web Interface) that allows the user to easily access your board via mobile phone, tablet, or PC.
PiGear Nano Raspberry Pi CM4 Nano-ITX carrier board is available for 169.00 Euros, or about 201.45 USD without module nor enclosure in the company’s store. A kit with a Raspberry Pi CM4 with 2GB, 16GB RAM, and no wireless module, plus a black enclosure goes for €230.50, possibly with VAT since the company, Dun Cat B.V., is incorporated in the Netherlands. More details may also be found in the announcement, and the user manual can be found in the store.
