Meadow F7v2 Feather

Our second iteration of the Meadow F7 board, and packing a number of upgrades, including:  64MB of Flash – This is an upgrade from 32MB in v1. Upgraded Antenna – Gives 10x better performance. Fully SMT-Compatible – The F7v2 has hybrid, castellated-header/IO mounts that allow for use as both a through-hole (PTH) device, as well as a surface mount device (SMD/SMT). I2S Sound – Added a full set of hardware IO for inter-integrated sound, which enables both I2S microphone input, and sound output. Low-power Timer Input – Includes a pin that has a low-power timer that can count pulses even while the board is asleep! Upgraded Silkscreen Design – New silk screen makes bus IO identification much easier. Fixed Battery Voltage – Upgraded the power components to make sure that the full 3.3V is available. Better Buttons – High-quality Wurth Elektronik buttons that have a greater surface area and a much nicer click. Technical Specs Powerful, energy-efficient STM32F7 microcontroller with WiF
