Glinker GY7508 RS232-SPI Module User Manual
The GY7508 is a single‑channel RS232 (UART) to SPI bus converter that provides a standard SPI master interface and optional slave mode. It operates from a +5 V supply, outputs 3.3 V TTL signals and supports SPI clock rates up to 12 MHz. The module includes pins for baud‑rate selection, power, ground and the four SPI signals (SCK, MISO, MOSI, CS0).
The manual details the hardware layout, pin definitions, electrical characteristics, baud‑rate configuration, and a full set of serial commands for configuring SPI mode, channel, clock frequency and performing Easy‑SPI read/write operations. Example code for common SPI devices such as EEPROMs and DACs is provided, along with timing diagrams and application schematics. This manual is written in Chinese.

Questions answered in Wuhan吉阳光电 manuals
What is the default serial baud rate if the COMSET pins are left floating?
The default baud rate is 115200 bps when the COMSET pins are not connected.
How many SPI channels does the GY7508 provide?
The GY7508 provides a single SPI channel (CS0).
How do I install the driver for the GY7501 adapter?
Connect the adapter to a PC USB port, then run the provided driver installer and select the driver folder as prompted.
What software is supplied with the GY7501 adapter?
The package includes the DCTools I2C utility, a DLL library with API functions, and Visual C++ example code.
What is the default serial baud rate of the GY7632 adapter?
The adapter ships with a default serial baud rate of 115200 bps.
How can the serial baud rate be changed?
Baud rate is selected by the COMSET0 and COMSET1 pins: shorting a pin to GND sets a ‘0’, leaving it floating sets a ‘1’. The combination determines the baud rate.
