Arduinonext is an initiative powered by an electronics and microcontrollers specialist team aiming to help all those who are entering in the technology world, using the well-known Arduino platform to take the next step in electronics.
We strive to bring you the necessary knowledge and experience for developing your own electronics applications; interacting with environment; measuring physical parameters; processing them and performing the necessary control actions.
This is the first title in the 'Hands-On' series in which Arduino platform co-founder, David Cuartielles, introduces board programming, and demonstrates the making of an 8-bit Sound Generator.
ESP32-C3-DevKitM-1 is an entry-level development board based on ESP32-C3-MINI-1, a module named for its small size. This board integrates complete Wi-Fi and Bluetooth LE functions. Most of the I/O pins on the ESP32-C3-MINI-1 module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-C3-DevKitM-1 on a breadboard. Specifications ESP32-C3-MINI-1 ESP32-C3-MINI-1 is a general-purpose Wi-Fi and Bluetooth LE combo module that comes with a PCB antenna. At the core of this module is ESP32-C3FN4, a chip that has an embedded flash of 4 MB. Since flash is packaged in the ESP32-C3FN4 chip, rather than integrated into the module, ESP32-C3-MINI-1 has a smaller package size. 5 V to 3.3 V LDO Power regulator that converts a 5 V supply into a 3.3 V output. 5 V Power On LED Turns on when the USB power is connected to the board. Pin Headers All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board. For details, please see Header Block. Boot Button Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port. Micro-USB Port USB interface. Power supply for the board as well as the communication interface between a computer and the ESP32-C3FN4 chip. Reset Button Press this button to restart the system.
