Raspberry Pi 4 is one of the most popular boards used both in professional environments as well as by people beginning their journey in the embedded world, that’s why it’s a must-have on a list of top 5 IoT development boards. It’s a low-cost, but quite powerful embedded board. RPi4 is equipped with a high-performance 64-bit quad-core processor - Broadcom BCM2711, which is a Cortex-A72 (ARM v8) 64-bit SoC. On top of it it is equipped with dual-display support, hardware video decode at up to 4Kp60, dual-band 2.4/5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, as well as PoE capability. Raspberry Pi 4 is one of the official reference devices of Mender. Take a look at our documentation on how to flash an SD card for Raspberry Pi and get started with OTA updates for Raspberry Pi 4.
