SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...

The BPI Bit (also referred to as BPI:bit, stylised as webduino:bit) is an ESP32 with Xtensa 32bit LX6 single/dual-core processor based embedded system. The board is 5 cm × 5 cm and has an ESP32 module with Xtensa 32bit LX6 single/dual-core processor, with a capacity of up to 600DMIPS, with a built-in 448KB ROM and 520 KB SRAM accelerometer and magnetometer sensors, 2.4G WiFi, Bluetooth and ...
A DB-25 connector as described in the RS-232 standard Data circuit-terminating equipment (DCE) and data terminal equipment (DTE) network. In telecommunications, RS-232 or Recommended Standard 232 [1] is a standard originally introduced in 1960 [2] for serial communication transmission of data.
