What is the difference between the MAX7219 and the MAX7221? The MAX7221 is a higher-performance version of the MAX7219, with additional features such as a serially-controlled shutdown mode and an on-chip BCD-to-7-segment decoder. However, it is generally more expensive than the MAX7219. For most of the nobby projects, my first preference is.

The MAX7219 and MAX7221 Led drivers Use Arduino for Projects
MAX7219 LED Display Driver (or MAX7221) if necessary soldering tools and solder Connection Let's take a look at the datasheet of the IC first. The connection with the Raspberry Pi looks like this: RPi Pin 2 (5V) => Pin 19 (V+) RPi Pin 2 (5V) with 10k ohm resistor => Pin 18 (ISET) RPi Pin 6 (GND) => Pin 4 and Pin 9 (GND) RPi Pin 19 => Pin 1 (DIN)
Electronic How to use MAX7219 with high current LEDs Valuable Tech Notes
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 8x8 static RAM that.
Interfacing MAX7219 LED Dot Matrix Display with Arduino
Yes, high impedanceis basically open circuit. "When the MAX7219 is in shutdown mode, the scan oscillator is halted, all segment current sources are pulled to ground, and all digit drivers are pulled to V+, thereby blanking the display. The MAX7221 is identical, except the drivers are high-impedance."
