NRF52840 is a high-performance, low-power wireless SoC chip launched by Norwegian Nordic Semiconductor. It supports multiple wireless protocols, including Bluetooth 5, Thread, Zigbee, ANT, and 2.4GHZ. The NRF52840 chip uses an ARM Cortex-M4F processor, clocked at 64MHZ, with built-in 1MB of flash memory and 256KB of RAM. It also has a variety of peripherals, including ADC, PWM, SPI, I2C, UART, USB and GPIO, etc. In addition, NRF52840 also supports a variety of security functions, such as AES encryption, SHA-256 hashing and True Random Number Generator (TRNG). Product Parameters Powerful wireless capabilities: Bluetooth 5.0, onboard antennaPowerful CPU: NRF52840 chip uses ARM Cortex-M4F processor, clocked at 64MHZ, built-in 1MB flash memory and 256KB RAMBattery charging chip: supports lithium battery charging and dischargingPower consumption: standby power consumption can reach 1mA.
warnWhen BOOST is connected, the charging current increases from 100ma to 300ma, and it can only be connected when the capacitor capacity is greater than 500mAh (to avoid explosion).
