Energy saving The ESP32 is a chip designed with TSMC technology for extremely low power consumption (ultra-low power management), allowing for the best power and performance with its high efficiency. As the quiescent current of the ESP32 chip is less than 5 μA it is particularly suitable for use with batteries or rechargeable batteries Compatible It has a similar pin layout to the conventional D1 Mini ESP8266-12F and is therefore pin-compatible with most accessories for it.

This is the SparkFun BLE Mate 2, an efficient and reliable Bluetooth 4.0 development board. The BLE Mate 2 closely resembles a breakout board, in that nearly every pin on the on-board BC118 module is made available to access. This board is actually a close cousin to our Gold and Silver Bluetooth Mates and functions in a very similar way but, as the name implies, operates as Bluetooth Low Energy instead of Bluetooth 2.0. The BLE Mate 2 offers a six-pin header on the end opposite the BC118 module which is used as a “host” serial pinout, the same as that on the FTDI Basic boards, which allows the BLE Mate 2 to be connected directly to any device with a matching header, such as the SparkFun Arduino Pro and Pro Mini. Coupled with the FTDI SmartBasic, you can even develop your code without having to swap cables! The board has built-in level translation, so it can be used with boards of higher voltage than the 3.3V default used by the BC118. Each BLE Mate 2 offers BC118 module that is capable of accepting and transmitting via the UART at 9600bps (default) with a frequency band of 2,402 MHz to 2,480 MHz. The SparkFun BLE Mate 2 only supports Bluetooth 4.0; it won’t connect to older devices. It’s also worth noting that BLE does not support a Serial Port Protocol as older versions of Bluetooth did; that makes interoperability between BLE dongles, devices, and modules harder than with Bluetooth Classic. |
