Introduction:
H1 is a cost-effective OLED frequency display module designed for continuous signal frequency measurement. It is primarily used for displaying frequency values in transceivers and other communication equipment, as well as for general frequency measurement applications.

Features:
1. Compact & User-Friendly: Small size, aesthetically pleasing display, simple circuit design, and dual-button control for intuitive operation.
2. High-Frequency Measurement: Core based on the dedicated SJ8K24P-T chip, supporting measurements up to 2.7 GHz.
3. High Sensitivity & Low Power: RF signal input via IPEX connector with high sensitivity and low operating current.
4.Power Management: On-board electronic power switch (can be disabled), ideal for battery-powered applications.
4. Precision Reference: Features a KDS/EPSON brand temperature-compensated voltage-controlled crystal oscillator (VC-TCXO) with ±2.5 ppm stability.
6. Advanced Algorithm: Unique gate control method and precise gate time calculation (non-timer interrupt) for high accuracy.
7. Configurable Display: Gate (display refresh) time: 0.64s / 1.0s, with real-time frequency value updates.
8. Resolution Options: Frequency measurement resolution: 100 Hz (0.64s gate) / 64 Hz (1.0s gate), with trailing digit blanking.
9. Dual IF Design: Two independent intermediate frequency (IF) settings. IF values and add/subtract modes can be preset separately without interference.
10. Data Output: UART serial output for measurement data, enabling secondary development.
11. Memory Storage: All settings automatically saved to EEPROM and loaded on power-up.

Specification:
- Gate Time: 0.64s / 1.0s

- Sensitivity: Varies with potentiometer adjustment (refer to manual for details)
- IF Settings
Dual independent IF design
IF Adjustment Step: 100 Hz
IF Range: 0 to 99.9999 MHz
Configurable add/subtract modes
Default IF value: 0 (displayed value = signal frequency)
- Frequency Reference
3.000 MHz VC-TCXO (KDS/EPSON, 3225 package)
Frequency stability: ±2.5 ppm
Operating Voltage: DC 8–10 V (9 V recommended)
Operating Current: ≤60 mA (tested at 9 V)
Display: 0.96-inch OLED, up to 8 digits
Dimensions: 27.3 × 27.8 × 19 mm (L × W × H)
Weight: ≈22 g
- Interfaces

1 x Power Cable (XH 2.54-2P, 15 cm)


Product Safety Information

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
