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.
Key Features
- SIMCom A7683E 4G LTE Module – LTE Cat 1 with up to 10 Mbps down / 5 Mbps up
- SIM Card Slot – Use any compatible nano/micro SIM with a data plan
- SMA Antenna Connector – Attach an external antenna (sold separately)
- 2 User Buttons – Labelled A and B for custom input
- STATUS and NET LEDs – Visual indicators for module state and network activity
- Qw/ST Connector – Qwiic / STEMMA QT I2C for solderless breakout connections
- Speaker/Microphone Headers – Unpopulated headers for audio expansion
- No Soldering Required – Pre-soldered socket header for direct Raspberry Pi attachment
Supported Frequency Bands
- LTE-FDD: B1 / B3 / B5 / B7 / B8 / B20 / B28
Ideal For
- Remote IoT sensor deployments
- Mobile and field projects without Wi-Fi
- Home automation with distant devices
- Connected art installations and festival projects
Package Contents
- 1× Clipper HAT Mini with pre-soldered header
Important: Antenna, SIM card, and Raspberry Pi are sold separately. An SMA antenna is required for operation.
Note: Check that your local carrier provides 4G LTE on the supported bands (B1/B3/B5/B7/B8/B20/B28) before purchasing. Coverage may be limited in North America.
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 over mobile networks. When a product offers 4G LTE connectivity, it can provide remote internet access where wired Ethernet or Wi-Fi is not available, given suitable coverage and a SIM or data plan.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering 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 (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- 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
- SMA is a small threaded coaxial (RF) connector widely used to attach antennas and other radio-frequency cables. A device with SMA antenna ports needs antennas or pigtails with matching SMA connectors, or a suitable adapter, to connect to them.
- 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.
