OBJEX Link v1.6 is the default version of the series. This version of OBJEX Link is designed to provide high computing power with the largest number of GPIOs. With the compromise of slightly increasing power consumption. The board is very compact and can be used for various IoT applications and more. It is possible to install two M0 modules or one M1 module. The board has been optimized for higher energy efficiency than other boards with the same microcontroller(ESP32-PICO-D4).
The test was done by running a web server on OBJEX Link v1.6, then trying to stress the board.
Ultra Deep Sleep
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 is currently an experimental prototype, but all components used are RoHS compliant.
OBJEX Link v1.6 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.
