It contains a Nordic nRF51822 Cortex M0 chip that comes integrated with BLE radio as well as most of the supporting circuitry and even a chip antenna. The whole thing is in a tin and comes with FCC, CE and TELEC certifications.Please note! The module comes with a blank chip - this is for people who are comfortable programming the chips themselves with a J-Link programmer and the Nordic SDK. We don't provide any firmware to go along with it!If you'd like to see a possible reference design for this module, check out the PCB files for our Bluefruit UART FriendThis is the same chip as the micro:bit, so there is micropython support as well as some basic Arduino support. Either way you go (SDK/micropython/Arduino) you'll still need to solder this onto a PCB and load code via a SWD programmer.TECHNICAL DETAILS-\n32-bit ARM® Cortex™ M0 CPU\nSupply: 1.8V – 3.6V\nMemory: 256kB Flash Memory, 32kB SRAM\nTx Power: +4 dBm @ 16mA\nRx Sensitivity: -93 dBm @ 13mA\nFlexible and configurable 31 GPIO\nInterfaces: UART / I2C / SPI / PWM\nOne 32 bit and two 16 bit timers with counter mode\nSPI Master / Slave\nTwo-wire Master (I2C compatible)\nUART (CTS/RTS)\nCPU independent Programmable Peripheral Interconnect (PPI) .
