The Clipper HAT Mini adds 4G LTE cellular connectivity to your Raspberry Pi, enabling data transmission over mobile networks — perfect for remote or mobile projects where Wi-Fi isn't available. Transmitting sensor readings and control data typically uses very little data, making a small pay-as-you-go plan go a long way.
Built around the SIMCom A7683E LTE module, it supports LTE Cat 1 with up to 10 Mbps downlink and 5 Mbps uplink. The mini HAT form factor includes LED status indicators, two user buttons, and a Qw/ST (Qwiic / STEMMA QT) connector for easy I2C breakout attachment. It plugs directly onto the Raspberry Pi's 40-pin header with no soldering required.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 4G LTE
- 4G LTE is a cellular data standard used for internet access through mobile networks. For this controller, LTE expansion matters when a project needs remote connectivity where wired Ethernet or Wi-Fi is not available.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- SMA
- A threaded coaxial connector commonly used for antennas. It matters because you need antennas with matching SMA connectors, or suitable adapters, for the LTE and GNSS antenna ports.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
