Does anyone have a part number for a suitable socket for development use? I have managed to track down ST's part number for the 100-pin early evaluation boards but not a suitable 48 pin variant. FYI Early revisions of ST's eval boards (e.g. STM3210B-EVAL) also have a /WS part number for ''with socket'' so that when the silicon is changed, the micro can be changed easily. They are very rare after product launch. Thanks!
My (usa) firm is building small pcbs holding STM32 (48,64 or 100 pin QFPs) small xtal, VReg, Caps, SOT Uart Level Shifter, and hi-capacity, 8 pin soic, spi eeprom. Mini JTAG and I/O connector - with optional 0.1'' adapter pcbs. Plan now is to build about 50 ea for our internal needs - can build more if the forum requests... Small qty. price is about cost of micro + 23 USD, fob usa - assembled/tested. This functional board should be less expensive than the mechanical, clamp connector you described...
