ESP8266 DevKit | 16x2 I2C LCD Display | Tutorial & Project
DevKit is a microprocessor-based development board developed by NodeMcu Team.
It contains ESP12E Wi-Fi Module, which integrates an ESP8266EX Wi-Fi
System-on-a-Chip (SoC). NodeMcu ESP8266 DevKit supports Two Wire Interface or I2C
communication by using the Wire library.
LoRa DevKit | LoRa Controlled Robot Car | Tutorial & Project
LoRa Controlled Robot
Car is built with Heltec ESP32 LoRa DevKit. It contains ESP32‑D0WDQ6
Wi-Fi System-on-a-Chip (SoC) and Semtech SX1276 LoRa Transceiver chip. The
board also has an 0.96" OLED display for displaying text, graphics and
images. LoRa is a spread spectrum modulation technique derived from Chirp Spread
Spectrum (CSS) technology. The Semtech SX1276 LoRa Transceiver chip feature the
LoRa long range modem that provides ultra-long range spread spectrum
communication and high interference immunity whilst minimizing current
consumption. It uses license-free sub-gigahertz radio frequency bands like
433MHz, 868MHz and 915MHz. LoRa enables very-long range transmissions with low
power consumption. LoRa Controlled Robot Car consists of a transmitter and
ESP8285 DevKit | Getting Started & Programming | Tutorial & Project
GETTING STARTED DOIT ESP8285 DevKit is
a microprocessor-based development board developed by DOIT.am. It contains
ESP-M2 Wi-Fi Module, which integrates an ESP8285 Wi-Fi System-on-a-Chip (SoC).
The chip is embedded with Tensilica Xtensa L106, 32-bit Microprocessor, which
has a 160KB of SRAM. The chip has an external 1MB SPI Flash Memory to store the
user program. It runs on the clock speed of 80MHz to 160MHz. It supports IEEE
802.11b/g/n wireless networking standards and operates on 2.4GHz frequency
band. It also supports WEP, WPA, and WPA2 security protocols. DOIT ESP8285
DevKit uses WCH CH340G chip, as a USB-to-Serial Convertor.
