OBJEX Link v1.7-C3 is the RISC-V version of the series. This version of OBJEX Link v1.7-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.
OBJEX Link v1.7-C3 is currently an experimental prototype, but all components used are RoHS compliant.
OBJEX Link v1.7-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.
