If you’ve been thinking about developing a wireless device, whether IoT or not, this ARGALI SIM C3 is an absolutely packed development board. It’s in the format of a Feather board, with an ESP32-C3 module plus a SIM7080 modem. So in one board you have wireless radios for Bluetooth/BLE, WiFi, GPS, Thread, Zigbee, Matter, and NB-LTE (CAT-M). This powerful combination of radios allows both low-power, short-range connections to wireless sensors or mesh networks, as well as low to medium-power long-range connections to WiFi and LTE for internet access.
A STEMMA QT connector opens up a huge range of sensors to prototype with, allowing you to easily build and test sensor networks. Additionally, a Li-Ion battery connector with charge control circuitry enables true wireless operation, with charging via USB-C or a separate 5V input. This could be used for energy harvesting, solar, or wired power — all taken care of for you so you can focus on developing your application.
This kit comes with three antennas, pin headers, and a Li-Ion battery (though check to make sure shipping batteries to your country is allowed without hassle). The Feather form factor additionally allows a huge range of FeatherWing add-on boards, both from suppliers like Adafruit as well as third-party developers — here on Tindie we have a great selection to check out!
If you’re looking to prototype or deploy an IoT or wireless device that leverages multiple radio stacks plus location data, the ARGALI SIM C3 looks like an awesome choice for quickly getting up to speed.
