Teensy
Head'em Up !
Finding pre-soldered headers turns out to be a big issue for non-header-solderers such as myself. Does anyone ask themselves how the Arduino got to be so popular ? Pre-soldered headers is part of the answer.

The Teensy 3.6 (as well as its sibling, the Teensy 3.5) is larger, faster and capable of more complex projects, especially with its onboard microSD card port. An upgraded ARM Cortex MCU (180MHz from 72MHz), more memory (1M from 256K)—as well as more RAM, EEPROM and accessible pins ...
$33.25 for the 3.6, $29 for the 3.5; both are a very capable little microcontrollers.

... About 35 mA [@5V], plus current for anything Teensy is driving, like more LEDs if you've connected any.
See RaspberryPi#RPiZeroW, which looks almost power-hungry in comparison ( 100ma@5V ).
