The CH34X family comprises widely used USB‑to‑serial chips manufactured by WCH (WinChipHead), commonly integrated into generic UNO R3, ESP8266, and ESP32 development boards.
TK01 XL LED
Digital
Active High
TK01's 10mm LED uses a precise resistor for safe 5V operation, compatible with 3.3V MCUs like ESP32, slightly dimmer than 5V UNO R3.
Datasheet PDF
Overview
The TK01 is equipped with a high-quality 10mm jumbo-sized LED, designed for versatile applications. The LED's anode pin interfaces with a digital signal pin, while the cathode pin is connected to ground via a precisely calculated series resistor. This resistor ensures the current is limited to the maximum safe level for the LED when powered by 5V MCU, optimizing brightness and protecting the component from damage.
As different LED colors require specific forward voltages, the resistor value is carefully selected for each variant to prevent overcurrent, which could otherwise destroy the LED in seconds. The TK01 XL LED is fully compatible with 3.3V logic microcontrollers, such as the ESP32 and Raspberry Pi, offering seamless integration with a slightly dimmer output compared to 5V microcontrollers like the Arduino UNO R3. This makes the TK01 an ideal choice for a wide range of electronics projects requiring reliable, high-visibility... Read More...
FAQ
What is the standard size for the Tinkerblock TK01 LED?
The Tinkerblock TK01 LED is an F10 LED, which means it has a diameter of 10mm. This makes it one of the largest LED sizes available.
Can the Tinkerblock TK01 LED work with both 3.3V and 5V microcontrollers (MCUs)?
Yes, the Tinkerblock TK01 LED is designed to work with both 3.3V and 5V MCUs. The resistor is calculated to ensure maximum brightness at 3.3V. When connected to a 5V MCU, the LED may appear slightly dimmer.
Can I connect the Tinkerblock TK01 LED to a Lonely Binary UNO R3's analog pin?
Yes, you can connect the Tinkerblock TK01 LED to any of the Arduino UNO R3's analog pins, as these pins can function as digital pins. However, digital pins cannot be used as analog inputs. Therefore, you can connect the LED to either digital or analog pins on the UNO R3 as needed.
