The BLUENRG-134 is a system-on-chip (SoC) designed and manufactured by STMicroelectronics to provide an integrated, low power Bluetooth low energy (BLE) radio system for a variety of consumer, industrial, medical, and other embedded applications. It offers an RISC-based processor core, calibrated RF, multiple on-board peripherals, and a digital signal processor. It features a 2.4GHz RF transceiver, an energy-saving protocol stack, and a digital audio integrated multi-ball (DIM) sniffer. The BLUENRG-134 also provides a range of power and frequency flexible I/Os to interface with external analog peripherals and sensors. It has a 1.8V to 3.6V operating supply voltage, a -40°C to 85°C temperature range, and a BLE stack that complies with Bluetooth 5.1. With these features, the BLUENRG-134 SoC can provide reliable and robust connection as well as fast data transfer.
