The **H1P3N-R** is an electronic part number typically associated with **Hantronix** or similar manufacturers of optoelectronic components, specifically **OLED (Organic Light-Emitting Diode)** character display modules. Below is a breakdown of the technical specifications, pinout, and key features of this component. --- ### 1. General Specifications The H1P3N-R is a character-type OLED display. Unlike standard LCDs, OLEDs are self-emissive and do not require a backlight, leading to higher contrast and lower power consumption. | Parameter | Specification | | :--- | :--- | | **Display Type** | OLED (Character) | | **Format** | 16 Characters x 2 Lines | | **Controller** | US2011 (or equivalent) | | **Interface** | Parallel (8-bit/4-bit) or SPI | | **Operating Voltage** | 3.3V to 5.0V | | **Emitting Color** | Red (indicated by the "-R" suffix) | --- ### 2. Pin Configuration (Typical 16-Pin) Most modules in this series follow the standard industrial character display pinout: | Pin No. | Symbol | Description | | :--- | :--- | :--- | | 1 | VSS | Ground (0V) | | 2 | VDD | Supply Voltage (+3.3V / +5V) | | 3 | NC | No Connection (or Contrast - often unused in OLED) | | 4 | RS | Register Select (Data/Instruction) | | 5 | R/W | Read/Write Select | | 6 | E | Enable Signal | | 7-14 | DB0-DB7 | Data Bus Lines | | 15 | NC | No Connection | | 16 | NC | No Connection | --- ### 3. Key Features * **High Contrast:** Since black pixels are completely "off," the contrast ratio is significantly higher than STN or FSTN LCDs. * **Wide Viewing Angle:** Offers nearly 180° visibility without color shifting. * **Fast Response:** OLEDs have microsecond response times, eliminating the "ghosting" effect seen on LCDs in cold temperatures. * **Thin Profile:** Lack of a backlight unit makes the module thinner and lighter. --- ### 4. Integration Example (Pseudo-Code) To interface this part with a microcontroller (like an Arduino or ESP32), you would typically use a library compatible with the **HD44780** or **US2011** driver. ```cpp #include // Initialize the library with the numbers of the interface pins // RS, E, D4, D5, D6, D7 LiquidCrystal lcd(12, 11, 5, 4, 3, 2); void setup() { lcd.begin(16, 2); // Set up the OLED's number of columns and rows lcd.print("OLED Red Ready"); } void loop() { // Cursor to second line lcd.setCursor(0, 1); lcd.print("H1P3N-R Active"); } ``` ---
