For an Arduino Uno, a typical connection is: VCC → 5V GND → GND D0 → SCK / D13 D1 → MOSI / D11 RES → Digital I/O DC → Digital I/O CS → Digital I/O The dedicated CS pin allows the OLED to share the SPI bus with other devices such as SD cards or additional SPI peripherals. 🔄 I2C / IIC Configuration On compatible versions, the module can be converted from SPI to I2C by changing the appropriate resistor configuration on the PCB. The supplied board configuration may require: Moving the resistor from R3 to R1 Shorting R8 with solder Using D0 as SCL Using D1 as SDA Configuring DC for the I2C address The exact resistor positions can vary between board revisions, so check the markings on your particular PCB before modification. 🎯 Applications Arduino projects ESP32 projects ESP8266 projects STM32 development Raspberry Pi projects IoT devices Sensor displays Voltage/current meters Battery monitors Temperature displays Digital clocks Data loggers Portable electronic devices Robotics DIY measuring instruments Embedded systems Menu and status displays 💡 Advantages of OLED OLED technology is self-emissive, meaning the pixels produce their own light and do not require a conventional backlight. This provides high contrast, compact construction and a wide viewing angle while keeping power consumption relatively low. ⚠️ Important Notes This is the 7-pin SPI version, not the 6-pin version. The module is normally configured for SPI communication. Check the PCB labels before connecting the module. Do not exceed the specified supply voltage. Although many versions support 5V operation, the exact voltage tolerance can vary between board revisions. I2C operation may require hardware resistor modification. The actual PCB layout and component markings may vary slightly between production batches. Display colour: Blue. Libraries such as Adafruit SSD1306 and U8g2 can be used with compatible microcontrollers. 📦 Package Includes 1 × 0.96 Inch Blue SPI OLED Display Module

Out of stockDigital Multimeter Small Yellow Color LCD AC DC Measuring Voltage Current
[Measuring Instruments] A multimeter or a multitester, also known as a VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance. Analog multimeters use a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made. Digital multimeters (DMM, DVOM) display the measured value in numerals, and may also display a bar of a length proportional to the quantity being measured. Digital multimeters are now far more common than analog ones, but analog multimeters are still preferable in some cases, for example when monitoring a rapidly-varying As the name suggests it is the multifunction device for all your testing need for daily work. When testing DC voltage, AC voltage, DC current, resistance, diode, buzzer, and battery, connect the red test lead to “VΩmA” jack and black test lead to “COM” jack, whereas When you need to test the current more than 200mA, connect the red test lead to “‘ 10A≡” jack and black test lead to “COM” jack. And When while testing the temperature, connect the temperature probe to “VΩmA” jack or “COM” jack. When testing the magnifying ratio of the transistor, turn the switch to hFE position and connect the transistor to the eight hole jack available in blue color. For the Square wave output, the frequency is 50Hz, the voltage is approximately 3Vp-p. The output jack is “VΩmA” and “COM” Description Table: Features : Small size makes it comfortable in many areas Brand new product. Good for newbies with basic knowledge of VI.
