Description

Summary

The RadioCore series is a quasi-system-level development platform that enables flexible integration of various MCUs and RF modules within an ultra-compact form factor, making it well suited for a wide range of IoT applications.

The RCC6-62, a model in this series, is equipped with the Espressif ESP32-C6 and SX1262， supports 2.4 GHz Wi-Fi, Bluetooth 5.0, BLE and LoRa connectivity.

The RCC6 features a custom pin layout that supports solder-free plugandplay operation, simplifying prototype assembly and module replacement, thereby accelerating development and iteration cycles.

It supports the official Arduino framework and is fully compatible with mainstream toolchains including PlatformIO, and ESPIDF, enabling developers to work in familiar environments and speed up project delivery.

FAQ

Does the device come with LoRa or Wi‑Fi HaLow modules?

If you select RCC6, it does not include long-range communication modules such as LoRa or Wi‑Fi HaLow.

RCC6‑62 is equipped with the SX1262 LoRa module.

Can I replace the RF module freely?

The RF module requires SMT mounting. Replacement is feasible if you have the SMT capability and solder the pins correctly.

Battery Power Supply

The main unit of the device does not come with a dedicated lithium battery interface. However, lithium battery power supply can be achieved in the following two ways:

There is a dedicated battery pin, VBAT, on the pin header.
We offer a matching baseboard for battery adaptation, which integrates a 1.25-2P lithium battery connector.
