[CH341A] [8 in 1] BIOS Programmer Set (1.8V / 3.3V / 5V) SPI Flash USB Programming Module + SOIC8/SOP8 Test Clip

Product Description:

CH341A Programmer Set for 24/25 Series USB Programming Module + SOIC8/SOP8 Test Clip with FT232BL Chip [1.8V adapter included]

This programming module set features the FT232BL chip with an external EEPROM (93C46), supporting Windows 10 and offering flexible power supply modes, including 5V and 3.3V external power options. The module is equipped with three indicator LEDs (TXD, RXD, and Power) and outputs for GND, RXD, TXD, 3.3V, and 5V through angled pin headers.

Designed for advanced users, the module includes solder points for additional function pins (CTS, RTS) and can connect to MCUs or other systems via standard pin connections. It simplifies in-circuit programming through its SOIC8/SOP8 test clip, which directly connects to chips for fast and efficient programming without desoldering.

Additionally, this programmer supports various chip series, including 24/25/26/93, and can work with multiple devices like computers, automotive MCUs, and mobile devices. The test clip provides reliable connections without the need for complex operations, ensuring user-friendly functionality while handling tasks like BIOS flashing and embedded system programming.

Product Features:

• Uses FT232BL chip with external EEPROM (93C46).
• Supports Windows 10.
• Supports three power supply modes: 5V external power supply, 3.3V external power supply, or powered by an external device (requires 3.3V-5V). Supports programming 1.8V chips with adapter.
• Equipped with 3 LEDs: TXD LED, RXD LED, POWER LED.
• GND, RXD, TXD, 3V3, and 5V: output via angled pin headers.
• Additional function pins: CTS and RTS reserved on the board for soldering.

Instructions (Example: connecting to an MCU):

• GND: Connect to GND.
• RXD: Connect to MCU TX (Signal flow: MCU TX >> FT232 >> PC RX).
• TXD: Connect to MCU RX (Signal flow: MCU RX << FT232 << PC TX).
• 3V3/5V: Outputs 3.3V or 5V (powered by USB, ensure the jumper is set to 3.3V or 5V).
• RTS: Connect to MCU CTS (Signal flow: MCU CTS << FT232 << PC RTS).
• CTS: Connect to MCU RTS (Signal flow: MCU RTS >> FT232 >> PC CTS).
