If you're interested in making your project connect to the web and be part of the grander scheme of IOT (Internet of Things) then this board is the gadget for you! Like other microcontrollers and microprocessors, the ESP32 now has built in power regulation circuits, on board antennas and noise filters and fits snuggly onto a breadboard for rapid prototyping. The ESP32 can interface with other MCUs as master or slave or function completely standalone through SPI/SDIO, I2C and UART. The microcontroller can also support an SD card and multiple sensors with its 32 GPIO pins (all of which can be used for PWM).

WIFI-ESP8266-B ESP8266 Adapter Board
US$3.49
This plain looking board allows users to connect ESP-01 Wi-Fi module to a FTDI chip or breadboard and program with 3.3 or 5vdc logic levels. This board has a ASM1117 IC that allows you to using the FTDI chip at any logic level making it easy for you to power the system and not worry about frying the ESP chip. The ESP8266 is popular and can be found in Sonoff wireless relays or server and can even act like an Arduino with the correct board manager and Arduino code. This adapter board helps to achieve all these functions and not worry about 3.3v logic level signals.

2633-ADA Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE)
US$34.92
The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready).

3231-ADA Adafruit LoRa Radio FeatherWing - RFM95W 900 MHz
US$34.92
This is the LoRa 9x @ 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings.
