Nordic Semiconductor has introduced the supply of their up to date nRF91 system in package deal (SiP) and improvement equipment. Builders can use these cellular-based units to allow IoT merchandise to hook up with LTE-M, NB-IoT, and DECT NR+ networks.
The nRF9161 SiP is an iteration of the prevailing nRF9160. This commonality means the brand new SiP comprises nRF9160 options like an Arm Cortex-M33 utility processor with 1 MB of flash, 245 KB of RAM, and Arm TrustZone know-how. That core has generic interfaces like SPI, I2C, UART, PWM, and a 12-bit ADC. The SiP additionally comprises a GNSS receiver, full LTE modem, RF Entrance Finish (RFFE), and energy administration system.

Nordic’s newer nRF9161 extends assist for world protection by including the B65 and B85 LTE bands. It additionally provides assist for DECT NR+, a non-5G mobile protocol. Nordic says DECT NR+ can allow long-range, scalable mesh functions.
One other enchancment is energy financial savings. The nRF9161 has up to date firmware that reduces the modem’s energy consumption. Nordic says that along with Energy Saving Mode (PSM) for roaming, the nRF9161 saves energy with a PSM-like sleep mode when linked to networks that don’t assist PSM.

You will get began with the nRF9161 SiP with the nRF9161 DK. This pre-certified improvement equipment comprises the SiP, antennas for mobile and GNSS, SWF connectors for measurements, SIM choices, and onboard SEGGER J-link for programming and debugging.
The nRF9161 DK ships with a SIM card pre-loaded with free information. Different SIM choices embrace a built-in nano/4FF SIM card slot, a footprint to plug in or solder (e)SIMs, or assist for Software program SIMs.
If you wish to add Wi-Fi 6 functionality to the nRF9161 DK, Nordic’s nRF7002 EK (analysis equipment) connects to the Arduino Uno-style pin headers. This analysis equipment has a dual-band nRF7002 Wi-Fi 6 companion IC. It could possibly additionally emulate the SSID location-only nRF7000 IC.

Nordic’s nRF Join for Desktop features a Fast Begin instrument and assist within the nRF Join SDK. The SDK additionally consists of examples of the nRF91 linked to an nRF70 chip.
Each merchandise are actually obtainable for cargo from electronics distributors, together with Avnet which has inventory and lists the nRF9161-DK for $128.77. Take a look at this nRF9161 DK product web page for extra info on the design equipment and hyperlinks to the SiP.
