Product Design

What does GND stand for?

GND stands for "Ground."

It is the reference point in an electrical circuit from which voltages are measured and provides a return path for electric current.

What does 5V 16MHz mean?

5V 16MHz refers to a voltage level of 5 volts and a clock frequency of 16 megahertz. It indicates the power supply and operating speed.

What types of memory does the microcontroller have?

• Flash memory (for storing programs)

• SRAM (for temporary variables during execution)

• EEPROM (for non-volatile storage that retains data even after power loss)

Which connection is used to program the ProMicro?

The USB port is used to program the ProMicro. It allows communication between the microcontroller and a computer for uploading code.

What is a microcontroller?

A microcontroller is a compact integrated circuit designed to perform specific tasks, with built-in memory, input/output ports, and a processor.

What is a microprocessor?

A central processing unit (CPU) on a single chip that performs arithmetic and logic operations, manages data flow, and controls other components in a computer system.

What do yellow pins on the PROMICRO represent?

Serial communication pins, specifically used for transmitting (TX) and receiving (RX) data.

What do red pins on the PROMICRO represent?

Power-related and analog input pins (A6-A9).

What do the green pins on the PROMICRO represent?

Additional analog input pins (A0-A3).

What do the purple pins on the PROMICRO represent?

SPI communication pins for high-speed data transfer (SCLK, MISO, MOSI).

What does LED stand for?

Light Emitting Diode

What is the voltage requirement for a LED?

About 2 volts and 15-20mA

What is the flat side of an LED for?

The flat side on an LED casing indicates the cathode (-) terminal, which is the negative side of the LED. This helps differentiate it from the anode (+) terminal, which is the positive side.

What is resistance measured in?

Ohms (Ω)

Can a resistor be placed any way around in a circuit?

Yes, resistors are bidirectional.

What does OLED stand for?

Organic light emitting diode

How many pixels is the screen capable of illuminating?

128 pixels wide by 64 pixels high (128 × 64)

What does 1.3 inch mean for an OLED, and where is it measured from?

The size of the screen; measured diagonally

What is the purpose of soldering?

PCB assembly, creating paths for electric signals in a circuit.

What temperature does solder melt at?

183–190°C (lead-based solder)

What is the point of tinning the tip?

Improves Heat Transfer, Prevents Oxidation, Extends Tip Life, Ensures Better Solder Flow

What is the purpose of a PCB?

It provides a surface for mounting components like resistors, capacitors, and microchips, while the conductive pathways, made of copper traces, create electrical connections between them.
