Nice board but not designed for low-power battery use
For GLYPH H2 – Zigbee Enabled ESP32H2 DEV Board
The GLYPH H2 has 80 uA Deep Sleep current, which will result in shorter battery life.
Otherwise, the board seems solid after limited Zigbee testing.
I have other H2 boards using the same Espressif module that sleep at 10 uA
