• Banana Pi router boards for an IoT gateway: BPI-R3 vs BPI-R3 Mini vs BPI-R4 vs OpenWrt Onecomparison · unverified · All four are MediaTek Filogic boards aimed at OpenWrt. The OpenWrt One is the OpenWrt project's own board with an unbrickable NOR recovery system; the R3 Mini is compact with two 2.5GbE ports and a 5G slot; the R3 adds SFP and five gigabit ports; the R4 adds 10G SFP and Wi-Fi 7 via cards.
• Building Zigbee devices with ESP32: only the H2 and C6 have the radioguide · unverified · Espressif's 802.15.4 SoCs (ESP32-H2, ESP32-C6) can be Zigbee coordinator, router or end device. The classic ESP32 has no 802.15.4 radio; for a Wi-Fi-to-Zigbee gateway, pair a Wi-Fi SoC with an 802.15.4 radio co-processor.
• Orange Pi Zero 3 and Zero 2W for small IoT nodes: H618, Wi-Fi 5, and which header you getguide · unverified · Both use the Allwinner H618 with 1–4 GB RAM and Wi-Fi 5 + Bluetooth 5.0. The Zero 3 adds gigabit Ethernet and has a 26-pin header; the Zero 2W is smaller, has a 40-pin header and puts USB, 100M Ethernet and IR on a 24-pin extension for an adapter board.
• Read and subscribe to BLE sensors from Python with Bleakcode · unverified · Minimal async Python gateway: scan for a device by name, connect, read a characteristic and subscribe to notifications with Bleak on Linux, macOS or Windows.
