Placa de Desarrollo de Microcontrolador USB Teensy 4.0
Descripción
- Placa de Desarrollo de Microcontrolador USB Teensy 4.0
- Soporta escalado de reloj dinámico
- Admite funciones de temporización Arduino
- Está diseñado para permitir cambios dinámicos de velocidad
- También proporciona una función de apagado
- Puede ser overclockeado, más allá de 600 MHz
La Placa de Desarrollo de Microcontrolador USB Teensy 4.0 es la última Teensy, que ofrece el microcontrolador más rápido y periféricos potentes en el factor de forma Teensy 1,4 por 0,7 pulgadas. Teensy 4.0 proporciona soporte para escalado de reloj dinámico.
A diferencia de los microcontroladores tradicionales, donde cambiar la velocidad del reloj causa velocidades de transmisión incorrectas y otros problemas, el hardware de Teensy 4.0 y el soporte de software de Teensyduino para las funciones de temporización de Arduino están diseñados para permitir cambios dinámicos de velocidad.
Teensy 4.0 también proporciona una función de apagado. Al conectar un botón pulsador al pin de encendido/apagado, la fuente de alimentación de 3,3V se puede desactivar por completo al mantener presionado el botón durante 5 segundos y volver a encenderla presionando brevemente el botón. Si una celda de monedas está conectada a VBAT, el RTC de Teensy 4.0 también continúa haciendo un seguimiento de la fecha y la hora mientras está apagado.

Fast, easy to use with a ton of peripherals and very reliable. The best microcontroller I've used so far, I mean, theres no perfect microcontroller, you just need to find one that matches the best to your application and this could be the one you are looking for advance applications with no doubt.
Quick delivery. Very powerfull device for a good price.
Livraison rapide. Appareil très puissant pour un bon prix.
Sauté d'Arduinos à cette plate-forme. C'est un excellent appareil. Beaucoup de puissance et de mémoire pour tout projet exigeant.
Je construis un robot auto-équilibré et, mais je n'ai pas pu atteindre les temps de cycle que je voulais avec l'Arduino Nano. Le logiciel du robot que j'essayais d'émuler fonctionnait sur un Rasp Pi, mais je ne voulais pas de cette complexité supplémentaire, j'ai donc essayé le Teensy 4.0. Fonctionnant à 600 MHz, j'ai immédiatement remarqué une nette amélioration des performances de stabilité de mon robot. La seule chose à surveiller est que le Teensy 4.0 n'est pas tolérant à 5 volts, vous devrez donc peut-être utiliser des convertisseurs de niveau logique. De plus, il y a beaucoup de documentation sur https://www.pjrc.com/teensy

Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- 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 RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A $100 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 RobotShop'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.

How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
- RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
- Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
