Powerful ESP32 microcontroller installed. Absolute novelty on the market Comfortable prototyping by simple programming via Lua script or in the for Arduino IDE and breadboard compatible design. This board has 2.4 GHz dual-mode Wi-Fi and Bluetooth chips from TSMC as well as the 40 nm low-power technology. The module has 38 pins and offers more functions than a 30 pin module. And it is smaller and more convenient to use. Brand ESP32 has integrated antenna and RF balance-unbalance former, power amplifier, low noise amplifier, filter and power management module. The entire solution occupies the smallest amount of printed circuit board area. The board is used with 2.4GHz dual-mode Wi-Fi and Bluetooth chips, adopts TSMC's 40nm low-power technology, has the best power supply and radio frequency characteristics, is safe and reliable, and can be extended to various applications. High cost performance. Small size, easy to embed in other products. Powerful, support LWIP protocol, Freertos. Support AP, STA, AP + STA three ways. Support Lua program, easy development.
