OBJEX Link v1.7-C3 RISCV
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.
IoT Applications: Wearable devices, Smart Home & Cities, IIOT, Predictive Maintenance, Agriculture Automation.
It's also ideal for rapid prototyping, advanced research projects, and robotics projects.

Block diagram - OBJEX Link v1.7-C3
The picture below shows the OBJEX Link v1.7-C3 pinout of its two M0 slots. As you can see some pins like SDA and SCL are present on both M0 slots in order to use at best all pins in the two slots.
The protoboard v2.0 can be used with OBJEX Link v1.7-C3, but the number/name of Pin/GPIOs in some cases does not match with the silkscreen.
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.
