Uses I2C 7-bit addresses between 0x60-0x80, selectable with jumpers
Interface: I2C
Note: Servos and Arduino are not included
The Adafruit 16-Channel 12-bit PWM/Servo Shield - I2C Interface comes with a fully tested and assembled shield as well as 4 pieces of 3x4 male straight header (for servo/LED plugs), a 2-pin terminal block (for power) and a stick of 0.1 inch header so you can plug into an Arduino. A little light soldering will be required to assemble and customize the board by attaching the desired headers but it is a 15-minute task that even a beginner can do.
Using only two I2C pins, control 16 free-running PWM outputs! You can even stack up 62 shields to control up to 992 PWM outputs. Because I2C is a shared bus you can also connect other I2C devices and sensors to the SCL/SDA pins as long as their addresses don't conflict (this shield has address 0x40).
There's an I2C-controlled PWM driver with a built-in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it to signal to tie up your microcontroller, it's completely free running. It is 5 V compliant, which means you can control it from a 3.3 V Arduino and still safely drive up to 6 V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)

The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RoboItchi's troubleshooting process or of a verified shipping error by RoboItchi.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A ¥10,000 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RoboItchi's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RoboItchi and ordered specifically to fulfill a customer request.
To request a return, submit a support ticket from your account under My Support Tickets to obtain a Return Authorization (RA) number. Returns without an RA number will be refused.
