Product Details
Introducing the FeatherS2 Neo, a top - notch ESP32 - S2 development board in Feather format from Unexpected Maker. This board is a real powerhouse! It comes with 4 MB of Flash memory for firmware and file storage, and 2 MB of QSPI - based external PSRAM, providing you with huge storage buffers.
This Feather has two 3.3V regulators. One is for the general operation of the board, ESP32 - S2, RAM, and Flash. The other LDO is for connecting external 3V3 modules, sensors, and peripherals. It has programmable EN control linked to GPIO21 and is connected to the S2's deep - sleep feature. When the S2 goes into deep sleep, the 2nd LDO shuts down automatically. Both regulators have ultra - low noise and quiescent current, with a maximum 700mA output.
The FeatherS2 Neo features onboard LiPo battery charging, 4MB of flash, an onboard RGB LED that can be turned off to cut deep - sleep current, and a 700mA output 3.3V regulator. It also has a 5x5 RGB LED Matrix with its own user - controlled LDO, so display content won't interfere with other 3.3V functions.
On top of the 320K SRAM, it has 2MB of extra PSRAM and 22 GPIO pins. And it comes with the popular STEMMA QT connector, a chainable I2C port. You can use it with any STEMMA QT sensors, accessories, OLEDs, inertial measurement units, and more. It's plug - and - play, thanks to its innovative design and compatibility with SparkFun Qwiic and Seeed Grove I2C boards.
The FeatherS2 Neo ships with a UF2 bootloader and the latest CircuitPython for ESP32 - S2. Just plug it into your computer, and it'll show up as a USB flash drive. You can copy or edit your code right on the drive. Coding a microcontroller has never been this easy! You can update CircuitPython from circuitpython.org as new versions come out. There's also early ESP - IDF and Arduino support for C++ coding.
Using the FeatherS2 Neo is a breeze. First, when you get it, plug it into your computer using a suitable cable. It will appear as a USB flash drive in your filesystem. You can then copy your code over or edit it directly on the drive. If you're using CircuitPython, just follow the updates on circuitpython.org to keep it up - to - date. For those who prefer C++, you can use the early ESP - IDF and Arduino support.
When it comes to connecting external devices, use the STEMMA QT connector. It's chainable, so you can connect multiple sensors and accessories easily. Just plug in a compatible cable and attach it to the board.
Regarding the battery, the FeatherS2 Neo has onboard LiPo battery charging. You don't need to worry about extra charging circuits. But remember, if you want to reduce power consumption during deep sleep, you can turn off the onboard RGB LED.
As for maintenance, keep the board in a dry and clean environment. Avoid exposing it to extreme temperatures or humidity. If you're not using it for a long time, it's a good idea to remove the battery to prevent potential damage.
