EH-ES201 is a low-power Bluetooth® 5 module based on Nordic nRF52 series platform. With ultra-small size and powerful features. Powered by a highly efficient 64MHz 32-bit ARM® Cortex ™ M4 CPU and 192 KB Flash + 24 KB RAM.
EH-ES201 comes with a high-performance built-in antenna, which can connect up to 60m in an open environment. No external antenna is needed, and the ultra-small size of 7.0 * 7.0 * 1.4mm can reduce the PCB area requirements of customers' products and help customers realize ultra-small products. At the same time, the ES201 module can optionally support external antennas to meet customer requirements for antenna performance and layout in different occasions.
After purchasing EH-ES201, we will provide free technical support for the APP of the IOS system or the APP of the Android system.
