The new RFM300H/RFM300 modules from HOPERF are based on the high performance CMOSTEK NextGenRF™ CMT2300 chip. They operate at 433/868/915MHz ISM bands, they have a high receiver sensitivity (–120dBm) coupled with +20dBm (RFM300H)/+13dBm (RFM300) output power ensures extended range and improved link performance.

The transfer speed can reach up to 300kbps@FSK and 40kbps@OOK, while module consumption stays at a very low value. The specialty of these modules is that there are 3 different types of modulations available in one chip, giving designers high flexibility in finding an optimal balance between transmission speed, reach and power consumption.

Moreover, the price of these modules is surprisingly low; please check our webshop for more information.
