LynKineser: Ligesom Kina, bare hurtigere

HQR1105, HQR1106

Vi holder et lille lager af ting fra Kina, men som der tit er brug for, og som det derfor kan betale sig at have på lager. Inspireret af Labitat's Ebay in a box.

Hvis du tager nogle af de sidste af en art, så bestil venligst nogle nye. Send faktura osv. til [email protected], så bliver du refunderet.

Herunder liste af ting, med kort beskrivelse/link til datasheet.
