OBJEX Link v1.6-C3 is the RISC-V version of the series. This version of OBJEX Link v1.6-C3 is based on the new ESP32-C3 which has a 32-bit single-core RISC-V processor. It's very useful for various IoT devices (wearables for example) and for applications that require higher power efficiency or other features such as Bluetooth 5.0, and WiFi 4.
This mode of operation of the board allows you to remove power from all components connected to 3V3. In order to use this mode of the board, it is sufficient to connect PWR_EN to Vbatt. You need an external module or for example the protoboard, you can manage the mode via software by developing a suitable module

Warranty & Certifications
OBJEX Link v1.6-C3 is currently an experimental prototype, but all components used are RoHS compliant.
OBJEX Link v1.6-C3 does not yet have all the certifications needed for mass sale. Currently, only a few prototypes are distributed for testing and research purposes, and not for real use on IoT devices.
