Atmosic Technologies has developed a reference design for a battery free solar-powered wireless keyboard with Primax Electronics in Taiwan.
The battery-free wireless keyboard reference design uses Atmosic’s low power ATM33 Bluetooth LE 5.3 SoC and PV cells to harvest indoor light and power the keyboard from a HSC (Hybrid Super Capacitor).
Primax (Zhisheng Technology) is a leading electronics equipment manufacturer in Taiwan and has developed a feedback touchpad can simulate vibration feedback based on the application, which is better than ordinary traditional designs and allows fingertips to feel a detailed tactile experience. It provides full-area clickable touch feedback with zero blind spots. Regardless of the size of the touchpad, it can provide uniform force and ensure that users get the most accurate and realistic feedback, creating a more immersive, intuitive and unforgettable interactive experience.

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 eliminates the use of batteries in the wireless keyboard reference design, benefiting the environment and helping save consumers time and money.
“Atmosic’s ATM33 has the best power efficiency on the market, making it an ideal choice for designing eco-friendly keyboards that reduce battery waste,” said Dylan Ko, Director of Product Marketing at Atmosic. “With Primax’s long and successful history as an ODM, this reference design will help leading OEMs accelerate their time-to-market while also meeting the growing consumer demand for sustainable products.”
“Most brands want to offer more sustainable designs. Cutting down on battery waste is a great place to start since this helps to significantly lower the carbon footprint of products,” said Sam Chan, Senior RD Director at Primax. “This new reference design helps companies to design keyboard products faster, even if they do not have expertise in that market, in a highly efficient, compact package so companies can offer sleek keyboard products.”
The Primax battery-free wireless keyboard reference design with Atmosic’s technology is available now for customers.
