![]() In general, the "generic" ESP32 DEV MODULE works fine. Open Terminal and execute the following command (copy->paste and hit enter): mkdir -p ~/Documents/Arduino/hardware/espressif & \Ĭd ~/Documents/Arduino/hardware/espressif & \Īfter that, restart Arduino IDE and it's done! You must see several boards on "TOOLS" Menu. ![]() In my case (MacOS), the installation is very simple: The novelty here is that Expressif itself in its GitHub, will give us the proper directions for library installation: arduino-esp32. Enter in this link: usb-to-uart-bridge-vcp-drivers and install the proper driver for your OS. It is important that you have installed on your computer, the updated CP210x USB to UART Driver. We will use the Arduino IDE to program our ESP32, same way we do with the ESP8266 family. Max data rate of 150 HT40, 72 HT20, 54 and 11 Maximum transmit power of 19.5 16.5 15.5 Minimum receiver sensitivity of -97 dBm.Supports sniffer, Station, SoftAP and Wi-Fi direct mode.Hardware accelerated encryption: AES/SHA2/Elliptical Curve Cryptography/RSA-4096.Supports external SPI flash up to 16 MB.OpenOCD debug interface with 32 kB TRAX buffer.PWM/timer input/output available on every GPIO pin.3 x UARTs, including hardware flow control.Onboard PCB antenna / IPEX connector for external antenna.16 MB flash, memory-mapped to the CPU code space.Integrated dual mode Bluetooth (classic and BLE).Integrated 802.11 b/g/n HT40 Wi-Fi transceiver, baseband, stack and LwIP.240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPS.Let's point its main properties in more details: And the good news is that Power Consumption is almost the same as ESP8266.īellow a chart that can show us its main characteristics, and differences when compared with ESP8266: Besides, the ESP32 has integrated WIFI, BLUETOOTH, DAC, several ADC (not only one as the ESP8266), capacitive touch sensors, etc (give a look at above block diagram). This feature will prevent some issues that happen with ESP8266, where the sole CPU needs stop controlling I/Os when handle with Comm. This board has a dual processed microprocessor that helps a lot, because when one processor is handle communication, the other one is in charge of I/O control, for example. The ESP32 is an under US$10 board with great advantages over similar IoT boards in the market.
