About Gadwave

Gadwave is an online store for maker electronics and robotics, run from Kalmar, Sweden. The store is operated by Arnvak AB.

What we sell

Raspberry Pi boards and official accessories, ESP32 and Seeed Studio XIAO microcontrollers, Meshtastic and LoRa devices, and touch panels for Home Assistant and Klipper. More sensors, modules and robotics are being added during the autumn.

How we work

We buy only from manufacturers and authorised distributors where we hold our own account. We keep little stock of our own. Some products are ordered from our distributor when you place your order, and others are sold as pre-orders. The delivery time is stated on the product page and again at checkout, so you always see it before you pay. Our Shipping policy lists the estimated delivery time for each region.

Your rights

You have a 14-day right of withdrawal on all orders and, as a consumer, a 3-year right to complain about faults under the Swedish Consumer Sales Act. See our Returns & Refunds policy for details.
