NHD - 0.6 - Breakout 是专门为 0.6 英寸彩色 OLED 玻璃(NHD - 0.6 - 6464G)设计的 breakout 板。它具有以下显著特点:
| Pin No. | Symbol | External Connection | Function Description |
|---|---|---|---|
| 1 | GND | Power Supply | Ground |
| 2 | 3V3 | Power Supply | Supply Voltage for OLED Logic (+3.3V) |
| 3 | DRV_VDD | Power Supply | Supply Voltage for boost converter (+5V) to drive OLED panel voltage (VCC). (Should be no connect if using pin 4 to apply external VCC) |
| 4 | N.C./VCC | - | No Connect by default. Can be configured for external VCC (+12V). (refer to On - Board Jumper Options table below) |
| 5 | SHDN# | MPU | Active LOW Shutdown control pin for boost converter (pulled HIGH via on - board 10kΩ resistor) |
| 6 | CS# | MPU | Active LOW Chip Select signal |
| 7 | RES# | MPU | Active LOW Reset signal |
| 8 | D/C# | MPU | Data/Command selection. LOW: Command. HIGH: Data |
| 9 | SCLK | MPU | Serial Clock Input signal |
| 10 | SDIN | MPU | Serial Data Input signal |
| 11 - 14 | GND | Power Supply | Ground |
| 15 - 26 | N.C. | - | No Connect |
工程师在使用时,需要根据实际需求正确连接引脚,确保电路正常工作。比如,在使用外部 (V_{cc}) 时,就要注意引脚 3 和 4 的连接配置。
| R9 | R10 | Description |
|---|---|---|
| Open | Close | (default) Boost converter circuit (+5V on pin 3) is used to provide VCC to OLED Glass. |
| R9 | R10 | Description |
|---|---|---|
| 用于为 OLED 面板提供外部电源电压 (V_{cc}) 的配置。 |
通过跳线选项,工程师可以灵活选择电源供应方式,以适应不同的应用场景。
| Item | Symbol | Condition | Min. | Typ. | Max. | Unit |
|---|---|---|---|---|---|---|
| Operating Temperature Range | (T_{OP}) | Absolute Max | -40 | - | +70 | (^{circ}C) |
| Storage Temperature Range | (T_{ST}) | Absolute Max | -40 | - | +85 | (^{circ}C) |
| Supply Voltage for OLED Logic | 3V3 | - | 2.8 | 3.0 | 3.5 | V |
| Supply Voltage for Boost Circuit | DRV_VDD | - | - | 5.0 | 5.5 | V |
| Supply Voltage for OLED Panel | (V_{CC}) | - | 11.5 | 12.0 | 12.5 | V |
这些电气特性为工程师在设计电路时提供了重要的参考依据。例如,在选择电源模块时,要确保其输出电压在规定的范围内,以保证 OLED 面板和其他电路元件的正常工作。
需要注意的是,不建议在未连接显示屏的情况下给板卡供电,否则可能会损坏升压电路,Newhaven Display 对此类损坏导致的 PCB 故障不承担责任。
该 breakout 板专门设计用于驱动和引出 NHD - 0.6 - 6464G 的信号。相关规格书可从 http://www.newhavendisplay.com/specs/NHD - 0.6 - 6464G.pdf 下载。
