As an LED driver, both several board options and several options can be used their connections. At the moment, the author of HyperHDR has implemented a high-speed serial driver Adalight port for boards ESP32 / Esp8266 / Raspberry Pi Pico RP2040. There are also several ways connections: Wled (Wi-Fi), Usb port and SPI bridge. You can find all the methods in the author's repository (link). For each driver, the software installation process and boards recommended by the author are described for purchase (beware of fakes and look at product reviews on the store page).
HyperSerialWLED - wireless connection, there is a slight delay.
HyperSerialEsp8266 / HyperSerialESP32 / HyperSerialPico - Usb wire connection.
Lower latency compared to WLED.
It is recommended to use when there is a long distance from the Raspberry Pi to the microcontroller.
HyperSPI - connection using Dupont jumpers. Least delay.
Recommended if the distance from the Raspberry Pi to the microcontroller is 15-20 cm.
My choice is connection via SPI bridge, the board was purchased by "RP2040-Zero" (link).
A level shifter (3.3->5V) is a mandatory part of the solution in which a GPIO device such as Raspberry Pi or ESP32 / Esp8266 / Raspberry Pi Pico RP2040 interfaces with the LED strip. The switch is based on the SN74AHCT125N chip (link).
Breadboard printed circuit boards are universal and indispensable elements for the purpose of quickly assembling circuits without the need to make your own printed circuit board (which complicates the project itself). For further assembly, a breadboard with dimensions of 3x7 cm (link) is suitable. I decided to approach the assembly in a non-standard way, bought a larger board and shortened it on all sides to the size I needed (with end processing).
In addition to the breadboard itself, we need additional elements:
- IDC socket (type "Female") (link),
- board socket straight (9 pin, type "Female") (link),
- pin plug 2.54mm (type "Male") (link),
- jumper-wire Dupont (type "Female-Female") (link).
