The MAX7219/MAX7221 are compact, serial input/output common-cathode display drivers that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8×8 static RAM that stores […]
Items Description This is another great IIC/I²C/TWI/SPI Serial Interface. As the pin resources of controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I²C interface module, you will be able to […]
INA219 DC Current Sensor Module Breakout Board I2C 26V 1. The programmable calibration register can be read in amps of DC and power in watts. 2. Up to 128 samples can be averaged to achieve filtering in a noisy environment. 3. The I2C interface has a timeout setting, which can […]
Infrared Emission Module IR Receiver Module 38KHz Infrared (IR) Receiver Module is a popular, low-cost, and easy to use wireless communication technology. IR light has a slightly longer wavelength than visible light, so This is undetectable by the human eye – perfect for wireless communication. A common modulation scheme for […]
Infrared Emission Module IR Transmitter Module This infrared transmitter module is basically a breakout board for an infrared LED with a few other passive components on the board. It includes a series current limiting resistor for the IR LED and a surface mount indication LED with it’s own current limiting […]
I2C Module has a inbuilt PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. These modules are currently supplied with a default I2C address of either 0x27 or 0x3F. To determine which version you have check the black I2C adaptor board on the underside […]
