The Talk² RPI HAT combines a robust ARM Cortex M3 MCU with a 4Mbit external SPI Flash, a CAN Bus Controller, two high-speed CAN Bus transceivers and a powerful RFM69W sub-GHz RF Module. All powered by a 5-30V Step-down Switching Regulator and a Dual 300mA LDO Regulator, offering one 5V and two 3.3V Rails.
The board is a standard Raspberry PI HAT, including the ID I²C EEPROM and expansion headers, so you can upgrade you Raspberry PI into an advanced and reliable wired/wireless Gateway for your IoT or any other microcontroller project.
Using this HAT you can easily create a link between your preferred MCU/Development Board, like Arduino, and the Internet. You can also back-power your RPI, so you don’t need to use an external A/C Adapter if you already have power your Bus.
