$200 Swarm M138 kit enables two - Low PIM Group Co.,Ltd

Sparkfun has launched a Satellite Transceiver Kit based on the Swarm M138 satellite and GNSS modem that allows low-bitrate two-way connectivity for IoT projects anywhere on earth.

Remote IoT applications have benefited from LPWAN standards such as LoRaWAN and NB-IoT, but in some extreme cases coverage may still be challenging, so satellite communication may be the only practical option. It used to be really expensive, but Swarm makes this more affordable, and companies like SigFox and Semtech also have (or had?) plans to use low-earth orbit satellites for their respective LPWAN technologies.

Swarm M138 kit content and specifications:

The solution is made possible by Swarm who aims to “connect people and devices anywhere, at all times, at the lowest cost” through its constellation of tiny satellites (11 x 11 x 2.8 cm each). Besides purchasing the hardware for around $200, you’ll also need to subscribe to a data plan with an annual contract for $60 US per year, or about $5 per month. The plan includes 750 data packets per month with each packet up to 192 bytes in size, so it’s definitely for IoT, but it still allows you to send one packet every hour for one year. If it’s not enough, you can stack up to 4 data plans allowing a single modem to use 3,000 packets for up to 576 KB per month.

You’ll find out how to get started with assembly, use a Python3 PyQt5 GUI for testing the commands in Windows or with a Raspberry Pi SBC, and learn how to write Arduino code for the Sparkfun Satellite Transceiver Kit in the hookup guide. Alternatively, you can check out the Arduino library repository on GitHub.

Sparkfun sells the Satellite Transceiver Kit – Swarm M138 for $195.95 plus shipping. So for the first year, you would need to spend around $260 together with the data plan.
