The PiSquare, an RP2040 & ESP-12E-based board, is a smart way to use multiple Raspberry Pi HATs without stacking on Raspberry Pi. Instead, PiSquare uses Socket programming to wirelessly communicate Multiple (“n” numbers of HATs) Raspberry Pi HATs. The PiSquare is an RP2040 & ESP-12E-based board, a smart way to use multiple Raspberry Pi HATs without stacking on Raspberry Pi. Instead, PiSquare uses Socket programming to communicate Multiple (“n” numbers of HATs) Raspberry Pi HATs wirelessly.”
You can find PiSquare very useful in several ways, as we were bound to use a single HAT on Raspberry Pi or a maximum of 3 Raspberry Pi HATs using PiStack. Still, you can’t connect the same HATs twice on it (like more than two UART or SPI-based Raspberry Pi HATs simultaneously). PiSquare lets you connect as many HATs as you want without stacking them on Raspberry Pi, whether SPI, I2C, or SPI HATs. You can operate all Raspberry Pi HATs wirelessly.

Shipping Policy
Fast Delivery! We ship via USPS, UPS, DHL, or FedEx because they're fast, reliable, and easy to track. We process orders within 24 hours, and delivery may take 4-7 working days, depending on your location. We'll email you the tracking info once we ship your order. We sell in USD.
Shipping Costs: For some products, we calculate shipping costs by weight rather than quantity. To reduce shipping costs for orders with multiple items, please contact us before placing your order.
Tariff: To minimize or avoid high tariffs, we ship from the country where the product is made, such as China, Italy, Taiwan, Canada, or Europe. If applicable, you will pay the tariff in your country before delivery. The total amount of your order does not include a tariff.
Ships From: On this product page, check the Ships From: label to see which country the product ships from. We do not ship all of our products from the USA, except for products made in the USA or in stock. We ship most products from regions such as China, Italy, Taiwan, and Europe, as well as other countries. Therefore, the tariff depends on the country of origin, as not all countries charge the same rate. For example, if the US imposes a 30% tariff on goods from China, in contrast, other countries may impose a lower tariff or none at all.
Tariff vs. Shipping Fee: Please don't confuse the shipping fee with the tariff, because they are two separate charges. You pay us a shipping fee for the carrier to deliver your order to your door. You pay the tariff to the customs office, a branch of your government, as an import tax.
Why aren't we adding tariffs to the product's retail price? If all countries imposed the same tariff amount and used the same currency, we would have added that tariff to the product's retail price. Our suppliers and we are not responsible for tariffs. Please shop accordingly.
Attention! We'll email you the tracking number so you can follow your parcel. The shipping company will contact you by phone, text, or email to arrange payment of the tariff on their website. As the customer, you're responsible for responding to their calls, texts, or emails. You can also use the tracking number link we emailed you to contact the shipping company or pay any applicable tariffs online, if you haven't already done so.
Heads Up! We're not responsible if the shipping company returns your parcel to the country of origin due to the unpaid tariff or non-compliance with its requirements. As a result, you will be responsible for the reshipping costs, applicable tariffs, and an additional 20% service fee. We will not accept any excuses for failing to follow up with the shipping company regarding the tariff, and we will not issue a refund.
Please check your SPAM folder! To provide you with delivery information, we will add your email address to the shipping website so you receive delivery notifications until your parcel reaches your shipping address. Please always check your spam folder to ensure you receive emails from Oz Robotics, USPS, UPS, DHL, and FedEx. Please let us know if you don't want us to enter your email on the shipping company website.
Return Policy
5 Hours: If a mistake occurs during purchase, you have 5 hours to request a refund for any reason, including if you don't want to pay the tariff. However, Stripe will not refund you its processing fee if you cancel your order; therefore, we cannot refund it.
All Sales Are Final: After 5 hours, we can't cancel your order with a refund because order cancellations incur multiple transaction processing fees from Stripe and PayPal, additional shipping fees, reverse tariff payments, and paid ads, all of which are costly and time-consuming. For technical issues, we'll assist you in resolving problems and provide a replacement if you can prove that the product has a manufacturing defect.
Exchange Policy: We want you to be happy with your new purchase. However, once you have used the product, we can't issue a refund, but we will offer an exchange for a product with irreversible manufacturing defects or technical issues. If you purchased the wrong product, then you will be responsible for the re-shipping fees and tariffs. If the product is defective, please email us ASAP with photos or a video of the faulty part so we can evaluate the issue before arranging a replacement.

Terms and Conditions
Delivery Date/Time: If the shipping company can't deliver your parcel because you weren't at your delivery address on the scheduled date/time, that is not our fault. If the carrier returned your parcel to the manufacturer from the country where it was shipped, that is outside our control. Therefore, you will be responsible for paying the re-shipping cost and any applicable tariff for any re-shipment request. In such a case, we will not issue a refund.
Warranty: We cover problems caused by manufacturing defects, not those resulting from faulty repair attempts, misuse, or customer accidents.
