The Spresense LTE Extension Board adds LTE connectivity to the Spresense main board and carries an onboard antenna and a nanoSIM cardholder. It also extends the interfaces of the Spresense main board with multiple mic inputs, a headphone jack, and a microSD card slot. The Spresense main board and the Spresense LTE extension board are connected by a board-to-board connector.
Compliant with LTE-M (LTE Cat-M1) and NB-IoT communication standards. Employs the Sony ALT1250 chipset, ensuring compliance with LTE-M (LTE Cat-M1) and NB-IoT communication standards. This enables developers to create systems and applications with low cost, low power consumption and wide-area coverage. (Compatible with US bands 2, 4, 12, 13; and EU bands 3 and 20)
Comes with a Truphone SIM so you can get started immediately.
Note: This is just the extension board. You'll need the main board as well.
Jargon buster
Plain-language definitions for the technical terms used above.
- LTE-M
- A low-power cellular data standard designed for Internet of Things devices rather than phones. It matters because the board needs LTE-M coverage and a suitable SIM plan in your area to send data over the mobile network.
- microSD card
- A microSD card is a small removable memory card used to store files such as audio tracks. For this product, the card is where the sound files live, so its capacity and formatting can affect how many sounds you can use.
- NB-IoT
- NB-IoT is a low-power cellular network standard designed for small amounts of data from remote devices. It matters for projects where the controller may need to send sensor readings from places without Wi-Fi or Ethernet.
