Propeller P1 Stacker for breadboards
P1 QFP is to nice looking to hide underneath.
The idea is that the dip sockets machined pins rim works as smt pads.
Most pins are brought out, some have additional features.
P13 8bit 500K spi ADC
P14 8bit 500K spi ADC
P15 I2C clk fastmode+ (2.2K pullup)
P16 I2C data fastmode+ (2.2K pullup)
P17 SPI clk (2.2K pullup)
P18 SPI mosi (2.2K pullup)
P19 SPI miso (100K pullup)
P20 SPI CSn_0 internal to ADC (100K pullup)
P21 SPI CSn_1 (100K pullup)
P22 SPI CSn_2 (100K pullup)
P29 LED shared with internal eeprom sda.
The ADC is the cheapest 2channel at $1, they probably have drop in replacement for 12bit and/or 1MHZ for a little more.
I'm sending away for 9 pcb (0.8mm 2layer) today, 100's probably three weeks later for ~$25.
Free China CP2102 "Prop plug" included.
