Ordering
The V2.0 board is available for US$20 per board plus shipping. Please note that this is for a bare board. Shipping for up to 4 boards is US$3 in the U.S. and Canada and US$5 in the rest of the world. This is for regular mail shipping from Canada which means there is no insurance and no guarantee on the delivery time.
Please note that regular mail service to the US has been quite irregular. The delivery time has been from less than 2 weeks to more than 4 weeks. If this is not acceptable, you can request Xpresspost service which will speed up delivery but will cost an additional US$12. Contact me for details and price.
New! Kits are now available. The complete kit is $90 and includes the board, all the electronic components, the mounting hardware, and the case with grommets (it does not include wires or connectors). The component kit is $73 and includes the board, all electronic components and the mounting hardware (it does not include the case, grommets, wires or connectors).
