Atmega328P SMD microcontroller
Atmega328P SMD microcontroller

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 ESP-12 WiFi Module
ESP8266 ESP-12 WiFi Module

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.


ESP32-WROOM-32D WiFi module
ESP32-WROOM-32D WiFi module

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.
