Microcontrollers and wireless MCU modules for products, prototypes and production runs. As a microcontroller supplier and microchips distributor, we list 32-bit Arm parts such as the STM32F407VGT6 and STM32H743ZIT6, the Raspberry Pi RP2040, 8-bit classics like the ATmega328P-AU, and Wi-Fi and Bluetooth modules such as the ESP32-S3-WROOM-1.
Many listings show real quantity price breaks, so the unit price you see in the cart follows the quantity you enter. Check the package, flash and RAM size, temperature grade and the full ordering code (suffixes often mean tape and reel or a different grade) against the manufacturer datasheet. If parts will be stored before assembly, check the moisture sensitivity level (MSL) in the datasheet and plan storage accordingly.
For the parts around the MCU, see analog, interface and sensor ICs and power semiconductors. Automotive-qualified controllers are in automotive semiconductors. For a production quantity or a part we do not list, send us the part number and volume.

Looking for a part we don't list? Request a chip. Need volume pricing? Request a bulk quote.
Yes. Quantity pricing appears only where real price breaks exist. For larger volumes, send the part numbers, quantities and delivery country with a bulk quote request and we reply with unit pricing for your volume, lead time and shipping options.
Electronic components (ICs, modules, reels, trays and tubes) cannot be returned once their sealed or moisture-barrier packaging has been opened. Items supplied to order, including backordered items and items with a minimum order quantity, are non-returnable unless they arrive defective or not as described. Contact us first for return instructions.
Yes. Specifications on our listings are summarized from manufacturer and listing information. Confirm critical specifications, the full ordering code and compatibility against the manufacturer datasheet or product page before purchase.
Yes. We ship worldwide. US orders ship at the rates in our shipping policy, and international shipping, duties and taxes are quoted before your order is confirmed, so you know the full delivered cost before you commit.
Use Request a Chip with the manufacturer, part number and quantity you need. We source parts beyond our listed catalog and will check availability and reply by email.
