BASIC Stamp 2 Module Ideal for beginners yet quite powerful, with BASIC Stamp 2p24/40 Modules - In addition to more speed and data a vast resource base and sample code. The BS2 is the core of our space, special commands support I/O polling, character LCDs, and BASIC Stamp 2px Module - Our fastest BASIC Stamp microcontroller 2 Stamps in Class program. I C and 1-Wire protocols. The BS2P40 has these features plus 16 supports the BS2p command set as well as special I/O configuration additional I/O pins. features. BASIC Stamp 2e Module - Perfect for those who have experience with the BASIC Stamp 2 and would like more data and program space.X-ON Electronics Largest Supplier of Electrical and Electronic Components Click to view similar products for System-On-Modules - SOM category: Click to view products by Parallax manufacturer: Other Similar products are found below : COMX-CORE-310 COMX-P4040-4G-ENP2 PICOIMX6U10R1GBNI4G PICOIMX6U10R1GBNI4GBW MC27561-TIGER MC27561- LION AM335XBBLK-SYSTEM MC27561-FOX CC-WMX6UL-SMPL CB-52-PUS-110-SX BD63725BEFV-EVK-002 5748-PJ-4AA-RI 5728-PJ-4AA-RI A00150 COMX P4080 A20-SOM-EVB RK3188-SOM RK3188-SOM-4GB 100-1225-1 PICOIMX6Q10R1GBNI4G Nit6Q PER-TAICX-A10-001 PER-TAIX2-A10-2280 EDL-mPCIe-MA2485 SOM-5897C7-U0A1E SOM-6896C7-U2A1E Q7M311-N4200- 4GB SCM180-Dual-2G Industrial SCM180-Quad-4G-Industrial 3354-HX-X38-RC 3359-GX-226-RC 5728-PJ-4AA-RC 6455-JE-3X5-RC Morph-IC-II ET876-X7LV IFC6301-10-P2 IFC6502-00-P1 IFC67A1-00-P1 IFC6701-00-P1 iW-G27M-SCQM-4L008G-E032G-BIG iW- G33M-SCMQ-4L002G-E008G-BII PWSE1000200B CS-DEPTHAI-04 MYC-C8MMQ6-8E2D-180-C MYC-Y7Z010-4E512D-667-I MYD- C4378-4E512D-100-I MOD5213-100IR A20-SOM A20-SOM204-1G A20-SOM204-1GS16ME16G-MC
