With Armbian we provide sane dvfs (dynamic voltage frequency scaling) settings that help a lot with throttling. When CPU or GPU cores are fully utilized H3 tends to overheat over time like any other popular ARM SoC released within the last 2-3 years. Adding to the usual SoC feature set (I2C, SPI, PWM, UART, SDIO, GPIO and so on) H3 has one USB OTG port, 3 real USB host ports (not exposed on all devices), Fast- and Gigabit Ethernet capablities (board specific), a Mali400MP2 GPU and Allwinner's video encoding/decoding engine. Same applies to status of mainlining kernel efforts. On the other hand some pretty cheap H3 boards were released that can be driven with rather low consumption and therefore combining H3 devices with a battery became a real use case with boards like Orange Pi One/Lite, NanoPi NEO and Neo AIR.Īs usual SoC and device information can be found in Linux-sunxi wiki. No PMIC means also that there is no battery charging/monitoring implemented so H3 is not that much suited for mobile devices. The H3 SoC from Allwinner is meant for OTT boxes and therefore its reference design is not accompanied by a separate PMIC (power management IC) unlike A series Allwinner SoCs (like A10, A20, A64.
