This chip has twice the flash, and four times the SRAM of its earlier sibling, the nRF52832 - 1 MB of FLASH and 256KB of SRAM. Compared to the nRF51, this board has 4-8 times more of everything. For this chip, we've added Arduino IDE support - you can program the nRF52840 chip directly to take full advantage of the Cortex-M4 processor, and then calling into the Nordic SoftDevice radio stack when you need to communicate over BLE. Since the underlying API and peripherals are the same for the '832 and '840, you can supercharge your older nRF52832 projects with the same exact code, with a single recompile!

Get a CLUE here at Adafruit by picking up this sensor-packed development board. We wanted to build some projects that have a small screen and a lot of sensors. To make it compatible with existing projects, we made it the same shape and size as the BBC micro:bit and with the same edge-connector on the bottom with 5 big pads so it will fit into your existing robot kit or 'bit add-on.

This ESP8266 IOT Weather Station Kit is based on esp8266 wifi function to achieve remote data transmission products, through the three sensors to collect temperature and humidity information and to achieve water droplets detection And UV intensity testing. Three sensor performance is very good, the first Crowtail- temperature & humidity sensor, which uses DHT11 sensor can simultaneously measure the temperature and humidity and then digital signal output. The water flow sensor can detect whether the outside is raining, and the last uv sensor can detect the UV intensity in the current environment.
