Overview

WitMotion JY-DATA-LOG is a serial data recorder module designed for high-speed serial data storage to an SD card. It works like a “black box”: data is saved in TXT format on the SD card, and parameters can be configured via a generated config.txt file. Two styles are available: JY-DATA-LOG (standard) and JY-DATA-LOG-BLE (Bluetooth/BLE version).

Key Features

  • Serial data storage to SD card (high-speed SD card logger)
  • 16KB large buffer/cache to help avoid data loss (stated as “16KB large buffer area, avoid data loss”)
  • Recorded files saved in .TXT format on the SD card
  • On first power-up with an SD card inserted, the module generates config.txt (includes baud rate parameters, etc.); recorder baud rate should match the IMU’s baud rate
  • Configuration and writing via config.txt (baud, pack/file numbering, file size limit)
  • Shield protection and multiple indicator light modes (easy to analyze)
  • Bluetooth SD Recorder (JY-DATA-LOG-BLE): remote modification by Bluetooth; Bluetooth can view real-time data recording and send transparent data; can set file size limit and data time stamp
  • PC software is provided for users to develop and test

Specifications

Name High-speed SD card recorder
Voltage 3.3V~5V
Current < 32mA
Interface Serial port TTL
Baud rate (Standard version) 2400-921600 (Default: 9600)
Baud rate (Bluetooth version) 460800 (Default: 9600)
Data rate (Standard version) 90KB/s
Data rate (Bluetooth version) 46KB/s

Weight (Standard version) 1.7g
Weight (Bluetooth version) 1.9g
Pad pitch (shown) 2.54mm
Mechanical markings (shown) 0.9mm; 0.8mm

Interface (Pin Definitions)

EN Power enable pin; pull high to make the module work; pull low to not work
GND Ground wire, negative power supply
VCC Power supply positive, input 3.3-5V
TX TTL sending pin
RX TTL receiving pin
D1 Cache alarm pin; pull high when the cache is less than 1KB; pull down when the cache is greater than 1KB

Configuration Notes (config.txt)

  • Example config line shown: baud=2,pack=1,FileSizeLimit:0
  • Baud list shown: 0:2400, 1:4800, 2:9600, 3:19200, 4:38400, 5:57600, 6:115200, 7:230400, 8:460800
  • Explanation shown (JY-DATA-LOG-BLE): baud=2 means baud rate is 9600
  • Explanation shown: pack=00006 means the next recorded file name is LOG00006.TXT (serial number automatically increments without manual modification)
  • Explanation shown: FileSizeLimit=0 means file size is not limited; if FileSizeLimit=1024, maximum is 1K data

Applications

  • TTL serial data logging to SD card for sensors and controllers (e.g., IMU serial data recording)
  • Debugging and test data capture where a compact SD card data logger module is needed
