The download link to the New Battery Chassis Schematic on the Wiki doesn’t work. And the Schematic Online Viewer also doesn’t work. Can someone fix the link.
I solve the problem, the wiki will sync after 1 to 2 hours.
you also can use this link to download it
The link now works, but there are a couple of problems.
First, it doesn’t appear to be a ZIP file. I was able to open it using 7zip as a RAR file.
Second, I looked at the PDF and it appears that it is not the NEW schematic. It does not show the Battery Fuel Gauge IC.
sorry, the link should is this: https://files.seeedstudio.com/wiki/Wio-Terminal-Battery-Chassis/res/WioTerminal_battry_650mAh.rar
But the problem is not solved yet!
I have been tried on other PC, all are working, please make sure your software is work or you try other PC or redownload it.
Need a new version of Winrar to open the file.
I cannot get the example sketch to work. The BQ27441 is not found on the I2C BUS. Other I2C devices like the BMP280 do work, but not the BQ27441.
