Choosing among microcontrollers & dev boards can be awkward when one board is Arduino-oriented and the other is a used embedded board with a different specification. The real choice is whether you prioritize a clearly named platform and lower listed price or a specific processor and memory/storage configuration. For a fast decision, PJRC Teensy 4.1 fits Arduino-centered builds and a new board at USD 30.00, while BeagleBone Black makes sense when its board-specific configuration matches your project brief despite the USD 49.99 price and Used condition.
Quick verdict
Choose PJRC Teensy 4.1 for an Arduino development board with Ethernet and SD card references, a New condition, and the lower listed price of USD 30.00. Choose BeagleBone Black when its embedded-board specification is the match you need; it is priced at USD 49.99 and marked Used. The USD 19.99 gap matters, but it is not the only dividing line: these boards target different project requirements.

Where each product wins
PJRC Teensy 4.1
PJRC Teensy 4.1 leads when an Arduino-centered build is the priority. Ethernet and SD card are named in its title, giving the category fit a concrete shape. If your project is organized around Arduino development and needs those named capabilities, this is the cleaner match. The clearly identified Teensy 4.1 model also makes it straightforward to specify in a parts list.
BeagleBone Black
BeagleBone Black leads when a project brief calls for its AM3358 or Cortex-A8 identity. Its title also spells out 512MB DDR3 and 8Gb SD as configuration markers, giving you specific terms to match rather than a vague promise. Pick it when those board details are central to the build, not simply because one technical number appears larger.
Product notes
PJRC Teensy 4.1 iMXRT1062
The PJRC Teensy 4.1 iMXRT1062 suits shoppers who want a clearly identified Teensy 4.1 model with an ARM core and Flash Memory feature. Its description also identifies 8 MB RAM, giving a concrete configuration detail to account for in a project plan without turning the number into a performance claim. The limitation is equally specific: 64 KB of flash memory is given for program storage. Treat that as a storage-planning input when defining software requirements. The board's United States origin is also stated, which may matter to shoppers who want that detail in their selection. Choose the Teensy when a defined microcontroller model is central to the build.
BeagleBone Black AM3358
BeagleBone Black AM3358 suits a project brief that calls for a board with the Cortex-A8 designation and embedded development format. The title gives 512MB DDR3 and 8Gb SD as concrete configuration markers, helping distinguish the intended hardware from a generic board description. The limitation is the package: the description says the device comes without a power cable, adapter, or accessories, and it may show scratches and dents. That means the purchase involves a bare device with visible-use considerations. Choose it when those named configuration details matter more than a ready-to-use package. For a project that does not depend on them, PJRC Teensy 4.1 presents a simpler decision.
Final choice by use case
- Choose PJRC Teensy 4.1 for Arduino-centered electronics projects, especially if Ethernet and SD-card wording matches your build and you want a New board at USD 30.00.
- Choose BeagleBone Black when a project brief is tied to its AM3358/Cortex-A8 identity or its 512MB DDR3 and 8Gb SD configuration, and the Used condition and bare-device package are acceptable.
- If your requirements are flexible: PJRC Teensy 4.1 is the simpler recommendation because its platform is named and its listed price is lower. BeagleBone Black is the more deliberate choice when its specific board configuration is the reason for buying.
