Displays comparison - OpenSourceEBike/TSDZ2_wiki GitHub Wiki

The recommended display is the 860C because our firmware can be installed without open it, has the best screen quality that improves reading on outdoors as also keeps the original water/rain resistance.

860C/850C and SW102 are very different displays, please see next tables to help you decide what may be the best for you.

860C/850C versus SW102

......Feature...... ......860C/850C...... ......SW102...... ......notes......
active firmware development yes and with room for new features and maintenance yes and with room for new features and maintenance
easy firmware install the most easy, no need to open the display making the process less risky to damage the display itself as also keeping the original water/rain resistance need to open the display (risky to damage and loose water/rain resistance); very small pads to solder the programming wires
display resolution and size 320*480 pixels, 3.2 inches 64*128 pixels, 1.3 inches
color display yes no
battery voltage 24V up to 52V (7S up to 14S) 24V up to 52V (7S up to 14S) TSDZ2 motor uses 24V up to 52V (7S up to 14S) battery packs so both 850C and SW102 work well with TSDZ2.
time clock yes no This feature may be important if you ride against time, like if you ride daily on the city and want to keep track of the time to arrive at work, etc. 860C/850C has a specific hardware to keep counting time even when it is disabled or when you remove the ebike battery.
USB charger yes no Can be useful if you are on a long trip and want to charge your mobile phone, 4G wifi router, lights, etc.
key pad buttons
  • 860C: 4
  • 850C: 3
 4 More buttons means easy access/more buttons combinations to access different menus on the display.
Bluetooth no yes
firmware update by wireless no yes Once you open the display and flash our bootloader, you then can update the firmware by Bluetooth, using your mobile phone your PC.
water resistance yes yes (IP65)

860C versus 850C

......Advantages...... ......Disadvantages......
860C
  • much better screen light/colors/gama that improves reading on outdoors (even more important for when using sunglasses)
  • bigger screen of 3.5 inches (although the resolution is the same)
  • buttons
    • 4 buttons instead of 3 buttons, meaning easier navigation
    • buttons are more robust
  • water resistance seems to be improved
  • the display is even bigger on width and height
  • for developers only: can not be opened without serious damage to the enclosure and risky to damage the board, that is needed to access to the JTAG debug connections
850C
  • for developers only: relatively easy to open the enclosure and access to the JTAG debug connections
  • the screen quality light/colors/gama seems somehow old technology
  • easy to permanently damage the UP/DOWN buttons by pulling them from the side by accident
