I'm under NDA, but I believe we can talk about things that have already been disclosed.
If you do a google image search for large micro:bit images, you'll see there's a Nordic NRF51822 chip (Which is an ARM Cortex M0, with BLE), and a Kinetis ARM chip connected to USB. It's running an mbed-compatible bootloader that appears as a USB mass storage device. You just copy hex files onto it and it programs the NRF51822.
- pfalcon 11y agoDoes that google image show any markings on "Kinetis ARM chip"?
- pfalcon 11y agoOk, Wikipedia says it's KL26Z, also 16K RAM, good. I was concerned there may be some cheating with higher RAM available on it. But nope, folks now will really need to optimize stuff to do something useful in 16K ;-).
