The SW102 is made for a Bafang, but Eco Cycles sells a special SW102 for TSDZ2, what you can use with stock FW and OSF for stock displays (v0.20 from mbrusa) without the need to flash the display itself.
Because this SW102 is special made for tsdz2, it is plug and play.
This SW102 display can not be used with a Bafang motor
Eco cycles sells these SW102 displays preflashed with a different communication protocol for tsdz2 and enabled bluetooth (like the eggrider display for Bafang has too)
So it it is eventually possible to flash Casainho's OSF without opening the display, by bluetooth, but in that case you can't go back to stock fw anymore.
