Please note: This part will be replaced by a USB module, coming soon.

At this time, we highly recommend purchasing the SX Tech Tool Kit PLUS or the SX Tech Tool Kit LITE. Both kits include the SX-Key programming tool, SX Tech Demo Board, two SX chips, serial cable, and cd-rom. The PLUS version includes 2 additional printed books over the LITE version. Click on the above product links for complete details.

The SX-Key is Parallax's primary development tool for the SX line of microcontrollers, supporting every chip that is commercially available. Supported by the SX-Key software, the SX-Key programming tool can program SX chips in-system and perform in-circuit source-level debugging. Also at the user's fingertips is an on-board programmable clock. The frequency output of this clock is adjusted from the software with a slider bar between 400 kHz and100 MHz. The software operates on a Windows platform and is compatible with Win98/NT/2K/XP platforms.
