It figures, Raytac launched nRF52820 & nRF52805 modules soon after Nordic released the SoC. As usual, all modules by Raytac are Bluetooth qualified and regulation pre-certified by FCC/IC/CE/SRRC/Telec/KC/SRRC/NCC. With both modules added on the list, whole nRF52 series module road map now has become comprehensive and completed.
#nRF52805 SolutionMDBT42T series designed for highly cost constrained.
Bluetooth applications not always tough and complicated.
Most cases, Bluetooth applications are brief and require simple bridge functionality only such as UART service for Bluetooth Low Energy (BLE) or SPP for Classic Bluetooth (BT3 or BT2). Raytac adopted Nordic nRF52 base line solutions (nRF52805 / nRF52810 / nRF52811 / nRF52820) offer a series of base line modules with different form factor and antenna options for selection.
Excepting modules, Raytac even developed a firmware pre-loaded modules for base line solution which is called as AT command module series. AT command module collected a list of most common command that transparent transmission may need. A well developed firmware pre-loaded modules bring developers or customer a quick access to Bluetooth. Simply deploy the module onto applications and projects can be benefited with the maximum flexibility, design free, time saving advantage.
Nordic announced their 6th multi-protocol solution of nRF52 series with nRF52820, which supports Bluetooth Low Energy (BLE), Bluetooth mesh, Thread, Zigbee and 2.4GHz proprietary wireless connectivity.
Like other nRF52 siblings, nRF52820 highlights a powerful 64MHz 32bit Arm Cortex-M4 processor, includes 256Kb Flash Memory and 32Kb RAM, features of Bluetooth 5.2, 5.1 and 5 including long range and high-throughput of 2Mbits per second, as well as direction finding, low energy power control and low energy isochronous channels.
A full speed (12Mbits per second) USB 2.0 interface and 1.7~5.5V operation voltage bring a wide range of commercial and industrial wireless applications to nRF52820. To support nRF52820’s development, Nordic released SoftDevice S112, a new memory-optimized central stack. S112 now released as a alpha and will have full SDK (SDK V16.0.0) support coming in Q2 2020.
