HAWK 370

The slotket that finally does it all.

A Slot 1 to Socket 370 adapter built to run every Socket 370 processor on one board - Mendocino, Coppermine, Tualatin, and VIA C3. Hard gold edge connector. Tested to 155 MHz FSB.

Not just a render - it's already running on camera. Watch the full build & test video → (and see what other retro builders are saying in the comments)

what you'd actually get

HAWK 370 slotket adapter, final look
Drop hawk370.webp next to this file to show it here.

This (Revision 1.2) is more or less the final look - matte black with white silk screen. Unfortunately, the color isn't customizable. Revision 1.5 offers mounting holes, spot for ESP32-C3 to wirelessly control CPU Throttle (optional), and 2.1V+ voltage unlock (optional).

WARNING
HAWK 370 does not have a VRM

optional: throttle control & live monitoring

HAWK 370 has reserved footprints for an ESP32-C3, so you can add software CPU throttling and live rail monitoring later.

Not included - solder-on footprint only

This is an optional upgrade, not part of the base adapter or the pricing below. The HAWK 370 works as a normal slotket with nothing populated on those pads; the ESP32-C3 itself isn't included.

if this shipped

Here's the plan: fully assembled adapters, sold in bundles or individually, through PCBWay Bazaar.
No kits (sadly) - customs and import rules made that difficult for us. However, we might be able to offer just the PCB.

This is what the pricing would look like.

Not included above: shipping, and any VAT, customs duty, or import tariff your country charges on arrival. Those extra charges are added on top and vary by destination - PCBWay Bazaar calculates and shows them at checkout when applicable, once this is real.

the moment of truth

This part isn't a real order - nothing is charged, nothing is sent. I just want to know how it feels to actually decide, not just say you're "interested."

Bundle 1 × HAWK 370
Price per adapter $135.00
Shipping calculated at checkout
VAT / customs / tariffs not included, may apply
Adapter subtotal $135.00
