Heltec ESP32 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 receiver.

DOIT ESP32 DevKit | Getting Started & Programming | Tutorial & Project
DOIT ESP32 DevKit is a microprocessor-based development board developed by DOIT.am. It contains ESP-WROOM-32 Wi-Fi Module, which integrates an ESP32‑D0WDQ6 Wi-Fi System-on-a-Chip (SoC). The chip is embedded with Tensilica Xtensa LX6, Dual Core 32-bit Microprocessor, which has a 520KB of SRAM and 448KB of EEPROM, which can be read and written with the EEPROM library. The chip has an external 4MB SPI Flash Memory to store the user program. It runs on the clock speed of 80MHz to 240MHz. It supports IEEE 802.11 b/g/n wireless networking standards and operates on 2.4GHz frequency band. It also supports WEP, WPA and WPA2 security protocols. It is compliant with Bluetooth v4.2 BR/EDR and BLE specifications. The chip also integrates a Hall Sensor and Capacitive Touch Sensor. DOIT ESP32 DevKit uses Silicon Labs CP2102 chip, as a USB-to-Serial Convertor.
