The Adafruit Industries LLC 4078 is an ultra-compact RF Transceiver Module designed for custom PCB applications requiring Bluetooth Low Energy. It is built around the Nordic nRF52840 Cortex M4 chip, which integrates a Bluetooth Low Energy radio, native USB support, and a chip antenna.
This module operates in the 2.4GHz frequency band and supports Bluetooth v5.0 with a data rate of 2Mbps. It offers a sensitivity of -103dBm and a power output of 8dBm. The module supports a wide operating voltage range from 1.7V to 5.5V and operates within a temperature range of -40°C to 85°C. It provides various serial interfaces including ADC, I²C, I²S, PWM, SPI, UART, and USB, eliminating the need for an external USB-to-serial converter.
Designed for surface mounting, this module requires a stencil and reflow soldering process due to its under-pads instead of castellated pads. It comes with FCC, CE, and TELEC certifications. The module is supplied with a blank chip, intended for users comfortable programming with the Nordic SDK and an SWD programmer. It is compatible with Arduino and CircuitPython environments, and also supported by MyNewt.
