These are suitable for DIY projects or Raspberry Pi pcb as the outside diameter is only 2.5mm that fits in the Raspberry Pi mounting holes

The IC control circuit and the LED point light source share a power supply. The control circuit and the RGB chip are integrated in a 5050 package component to form a complete externally controlled pixel point.

NFC NTAG213 tag stickers are small adhesive tags that use Near Field Communication (NFC) technology to wirelessly transfer data when placed close to a compatible device, like a smartphone.

PiPower 5 Raspberry Pi 5/4B/3B+/Zero 2 W UPS HAT, 5V/5A Power Supply with Battery Backup, Safe Shutdown, Smart Alerts&Monitoring, USB-C PD 45W, Smart Power Management for NAS, Server, Home Assistant

This handy little USB thingymajig allows you to power your Raspberry Pi Touch Display 2 from a USB port, keeping your GPIO pins free for HATs or jumper wires.

This is a common model esp-01 breadboard adapter for esp8266 serial to WiFi transceiver module. Because the pin arrangement of esp-01 is not breadboard friendly and has no label, it is not convenient for rapid prototyping.

Tired of holding down a button every time you want to flash your ESP-01 or ESP-01S? This little adapter takes care of that for you. It uses the CP2104 USB-to-serial chip along with an auto-download circuit, so your module drops into flash mode automatically — just plug in, hit upload, and you're good to go.

The enclosure supports both landscape and portrait orientations with integrated cable management offering multiple cable exit points. It's also wall mountable, and includes a gap to ensure airflow from the rear of the case.

The ESP32-S3-Touch-LCD-4.3B is an all-in-one HMI development board featuring a 4.3-inch 800×480 IPS capacitive touch display driven by an ESP32-S3 dual-core LX7 microcontroller (240MHz). Equipped with 16MB Flash and 8MB PSRAM, it easily powers advanced GUIs like LVGL. Built for industrial applications, it incorporates isolated Digital I/O, CAN, RS485, I2C, TF card storage, RTC, and a wide-range 7–36V DC power supply with battery fallback. Flexible screw terminal options make integration into DIN-rail setups or custom enclosures effortless.

echnology isn’t just something you buy — you can build it yourself! With a bit of know-how you can 3D print moulds to make personalised soap bars, control a robot arm, add sensors and reactive LEDs to an old quilt, or anything else you put your mind to.
