OBJEX Link v1.5
OBJEX Link v1.5 is the default version of the series. This version of OBJEX Link is designed to provide high computing power. 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.
IoT Applications: Smart Home & Cities, IIOT, Predictive Maintenance, Agriculture Automation.
It's also ideal for rapid prototyping, advanced research projects, and robotics projects.
- Compact size 24x24mm, high component density
- Modular design for a wide range of applications
- Designed to ensure easy reuse
- Based on ESP32-PICO-D4
- WiFi & BLE 4.2 connectivity
- Over 17 GPIOs
- USB-C Type 2.0
- Tiny battery connector
- Compatible with Arduino IDE
- Battery manager(fast-charge)
- Support for external PSRAM
OBJEX Link v1.5 is not compatible with MicroPython.
