O2 Booster Board project prices for PC boards and parts

The O2 Booster Board plugs into the U3 and U4 IC sockets on NwAvGuy's O2 PC board in place of the NJM4556A chips.  It slides into the top slot of the same B2-080 case the O2 uses, and still leaves room for the batteries (or ODAC) in the case..  The O2 Booster Board is nearly all surface mount parts, although the parts used are the larger "1206" size.  The Booster Board also has three wires that have to be soldered onto places on the O2 board.

Sorry but no parts kits for sale due to the chances of getting a bad part and having to re-ship, plus the time and cost involved in bagging up everything and labeling it. You get your money’s worth from Mouser and Digikey! Everything labeled, static sensitive stuff is in proper anti-static bags, and (at least in the US) Mouser is good about sending out replacements for defective parts for free. The BOM with all the part numbers is posted at the project Google Drive link in post #1 of the project thread, with part numbers at Mouser and Digikey Electronics, plus a few at Allied Electronics and the Farnell UK site. If you find a BOM part is out of stock at the distributors, please let me know. I can probably help you locate an alternate part number.

Shipping is actual cost, which for US destinations (for all except the fully assembled Super CMOY board) is the USPS "first class parcel" rate of $2.70 and does include tracking. The post office says 3-5 business days on average to deliver "first class parcels" (goes by truck), but from my experience expect 5-10 business days.

For the fully assembled Booster Board the shipping to US destinations is via the USPS "priority mail small flat rate box" service which they charge $6.90 for, and includes tracking and postal insurance. The priority mail also gets there pretty reliably in 2 or 3 days (goes by air). The rigid box protects the fully assembled board and the postal insurance covers it in case they loose the package.

For destinations outside the US our post office here unfortunately is rather pricey. Their lowest rate is "first class international small package", which they say typically takes 10-14 days, for $13.50 ($13.35 + $0.15 for the padded envelope). The customs form number will actually work as tracking, just enter it in at the USPS.com website tracking page, but the tracking usually stops when the package leaves the US. The "first class international small package" rate is OK for bare boards, but for assembled amps that are thicker their next step up may be required, depending up the country, which is "first class international medium package" for $22.50 up to a certain weight and size. That one does include tracking to some countries. Again these are actual cost, no markup, and should be listed out at usps.com. Sorry but I have to declare the full value of the invoice on the customs form. Some countries charge (fairly large!) taxes on incoming shipments, so please check into your country's rules to avoid a surprise.

Payment via paypal, please PM me for the paypal address. The paypal fee also has to be added to the order, 2.9% of the total + $0.50 for orders in the US, 3.9% + $0.60 for outside of the US. Please make sure you are having paypal transfer the money into US dollars. I only accept paypal, sorry no checks or other payment methods.

Example 1: O2 Booster Board bare PCB with standard pins and wire, shipping to the US = $15.00 + $2.70 (US first class parcel shipping) + $1.01 (US paypal fee 2.9% + $0.50) = $18.71.

Example 2: O2 Booster Board bare PCB with standard pins and wire, shipping to the UK = $15.00 + $13.50 (intl shipping) + $1.71 (international paypal fee 3.9% + $0.6) = $30.21. Please make sure to specify for paypal to deliver the payment in US dollars.

Example 3: Fully assembled and tested O2 Booster Board with standard pins, shipping to the US = $119 + $6.90 (US "priority mail small box flat rate") + $4.15(US paypal fee) = $130.05.

Please contact me at the "contact" link for the paypal address if you wish to order.
