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 ...

ATmega328, ESP32, ESP8266, STM32 Soldered Electronics Inexpensive series of fully compatible Arduino boards for education and hobbyists, designed and manufactured in Croatia. Cardboarduino [166] ATmega168 [39] Inspired by the Paperduino, an ultra low-cost Arduino compatible, built on printed posterboard, rather than a PCB. Crumbuino-Nano [167 ...
NodeMCU was created shortly after the ESP8266 came out. On December 30, 2013, Espressif Systems [6] began production of the ESP8266. [12] NodeMCU started on 13 Oct 2014, when Hong committed the first file of nodemcu-firmware to GitHub. [13]
