Popis:	An extended version of the CALICE silicon-tungsten ECAL was tested in November 2021 at the DESY beam test facility. With 15 active layers, it featured some with a thin PCB design, and a new compact DAQ system handling all layers in a common set. The noise, self-trigger performances and response to punch-though electrons, without tungsten absorbers, have been evaluated for each of the 15360 channels, using an improved procedure. Showers of low-energy electrons (1 to 6 GeV) have been recorded in two configurations of absorber, and are being analysed. Some preliminary results at the cell level will be presented.
