Microcontrollers

Well known and popular 8-bit Atmel microcontroller which is used on the majority of modern Arduino boards as well as on Dasduino. This one is the SMD version, just as the one on Dasduino, which is used for soldering on PCBs and for usage in projects.

ESP8266 is an IC that delivers a true revolution in the world of makers, especially in the world of IoT (Internet of Things). This is a complete 32-bit SoC (System on Chip) with built-in flash memory, frame and EEPROM which can even be programmed directly from the Arduino interface, without the need for additional micro-controller. With all this, the most important point is that in itself has a built-in WiFi (AP, STA, AP + STA), all that for “little money”.

ESP8266 in this form (ESP-12) is suitable for direct soldering to a printed circuit board as an SMD component or directly solder the wires since the pin has its holes. It also comes with a PCB trace antenna.

Note: ESP8266 is an IC that works at 3.3V! Connecting directly to 5V, or track Arduino or Croduino plate will destroy it! Use logic level converter.

The ESP32 is a more advanced successor to the well-known ESP8266. It is a SoC (System on Chip) that can function as a standalone microcontroller and has everything you need on WiFi and Bluetooth 4.0 (BLE 4.0, low-energy) communication. With nearly 30 I / O pins and low power consumption, ESP32 will almost certainly be the leader in the Internet of Things for years to come.

The microcontroller itself works at a frequency of 160MHz (up to 240MHz), while the module has a built-in flash memory of 4MB. It has all the classic protocols like 4x SPI, 2x I2C, 4x UART, and there are many built-in peripherals like 18x 12-bit ADC, 2x 8-bit DAC, 10x capacitive touch GPIO, temperature sensor, SD card controller, Ethernet interface, PWM, etc. The list is really long. It should not be forgotten that this module has FCC certification and PCB trace antenna.

ESP32-WROVER is a powerful microcontroller which has the possibility of wide application as it is possible to modify the processor clock and use its substantial memory. For these reasons, ESP32-WROVER can be used not only in conditions where low power consumption is required but also in situations where high speed is required to process large amounts of data.

The ESP32-WROVER comes with a PCB antenna and offers WiFi and Bluetooth 4.2 connectivity. The core of the module is the ESP32-D0WDQ6 chip. The operating frequency ranges from 80MHz up to 240MHz and the microcontroller can be used with 4MB of flash memory. The freeRTOS operating system drives the ESP32.
