The certified WB2072-00 module from Jorjin is a wireless MCU (microcontroller) module targeting Bluetooth 5.2 low energy applications. It is based on the STMicroelectronics BlueNRG-355AC wireless MCU QFN-32 package chip. The module is a cost-effective, ultra-low power, 2,4 GHz RF device.
Very low active RF and MCU current and low-power mode current consumption provide excellent battery lifetime and allow for operation on small coin cell batteries and in energy harvesting applications. Key features include:
• High-performance and ultra-low power Cortex M0+ 32-bit, 64 MHz.
• 256 KB Flash, 64 KB SRAM, 1 KB OTP, 7 KB MPU.
• Operating supply voltage from 1,7 to 3,6 V.
• Dynamic current consumption of 18 μA/MHz.
• Extensive peripheral set: 2 x SPI/I²S, 1x SPI, 2 x I²C, 1 x USART, 1 x UART, 6 x PWM, 1 x PDM, 1 x 12-bit ADC.
• Embedded UART bootloader.
• Enhanced security mechanisms such as: Flash read/write protection; SWD access can be disabled; secure bootloader.
• LGA 42-pin package measuring 15 mm(L) x 11 mm(W) x 2,6 mm(H).
• Temperature range of -40°C to +85°C.
