Atmosic Technologies announced a partnership with Primax to jointly develop a highly efficient photovoltaic (PV) battery free keyboard reference design using Atmosic's ultra-low power ATM33 Bluetooth LE 5.3 SoC. Using PV cells to harvest indoor light and power the keyboard, the user no longer needs to worry about changing batteries, both reducing the ecological footprint of the design and eliminating the inconveniences for the consumer when battery changes are required. Designed around Atmosic's ultra- low-low power ATM33e SoC, the keyboard can operate all day long by harvesting energy from indoor lighting.

The Atmosic ATM33e SoC includes an integrated energy harvesting power management unit (PMU) which uses the energy from the PV cell directly and manages energy storage elements ensuring the keyboard is always operational. The combination of low-power Bluetooth LE operation with the integrated PMU maximizing the efficient use of harvested energy reduces the size of PV cells needed for a full day of operation. This solution eliminates the use of batteries in the keyboard reference design, benefiting the environment and helping save consumers time and money.
