The boards are attractive because they offer a combining a powerful (600MHz dual-issue superscaler) processor processor and Arduino compatibility, and were designed and were being manufactured by PJRC in Oregon.
“PJRC and SparkFun have enjoyed a relationship for several years and we are looking forward to continuing to work together,” according to PJRC. “We’re taking this step with two main goals: As Teensy continues to grow, SparkFun has the manufacturing capability and sales teams needed to support that growth, and to allow PJRC to focus on software development and the electronics community.”
“The overlap of SparkFun and PJRC’s community makes this partnership a natural fit, as engineers and developers can now explore both companies’’ecosystems in one place, while each company can leverage its relative strengths to better serve those customers,” said SparkFun. “Technical support and engagement will continue to be provided through the PJRC forum.”
As well as direct sales, SparkFun will sell to other distributors “so you can continue to buy from stores which currently carry Teensy”, it said.
An NXP MMXRT1062 MCU is at the heart of both boards.
4.1 (above) is the larger of the two, and includes 8Mbyte flash, an 10/100 Ethernet PHY brought out to six pins and USB host (with power management) of five pins, as well as a micro SD card socket. There are a total of 55 IO pins.
4.0 (left) has 2Mbyte flash, no Ethernet, USB host on two pins and a total of 40 IO pins.
Both come in lockable versions to protect sensitive code, and also have CAN, CAN FD, I2S, S/PDIF and SPI interfaces.
As well as compatibility with the Arduino IDE (Teensyduino is the add-on programming environment), the boards are supported by
Microsoft Visual Studio (Visual Micro), PlatformIO and CircuitPython.
