Three new modules from Hezhao: Air780EHM, Air780EHV, Air780EGH offer features such as abundant resources, comprehensive audio capabilities, and integrated communication and positioning, providing a new low-power solution for industry applications.
Engineers in the community often ask: When will there be supporting boards available? The previous Air780EPM development board was too large; we want something smaller! Currently in the debugging phase, we need something more convenient for testing…
—— Here it comes!!! The development board was too big, and the new core boards are now available~ One not enough?
Then all three are launched simultaneously, available for immediate supply without waiting.
Air780EHM/EHV/EGH core boards, all pins fully exposed, with documentation open and continuously updated.

– Air780EHM Core Board –
-
Supports AirUI, Chinese fonts, and touch screens;
-
Powerful secondary development resources: 8MB Flash + 8MB RAM;
-
Supports 38 GPIOs, multiple SPI/I2C/PWM and other peripheral interfaces;
-
More than 10 additional API functions compared to Air780EPM…
Selection Tips: The Air780EHM is fully pin-compatible with the Air780EPM, adding support for UI on top of the Air780EPM, with larger resources, making UI development faster and more convenient.
When the Air780EPM cannot meet project requirements due to insufficient resources—— it can be directly upgraded and replaced with the Air780EHM.
