+Introducing the FeatherS2 (**Pre-Release**) - The PRO ESP32-S2 based development board in a Feather format!
+
+**Features & Specifications**
+ - 32-bit 240 MHz single-core processor 
+ - 16 MB SPI Flash
+ - 8 MB extra PSRAM
+ - 2.4 GHz Wi-Fi - 802.11b/g/n
+ - 3D antenna
+ - 2x 700 mA 3.3 V LDO regulator
+ - Optimised power path for low-power battery usage
+ - LiPo battery management
+ - Power (red), Charge (orange) & IO13 (blue) LEDs
+ - 21x GPIO
+ - USB-C
+ - APA102 RGB LED (CLK IO45, DATA IO40)
+ - ALS-PT19 Ambient Light Sensor (IO14)
+ - QWIIC/STEMMA connector
+ - Feather format
+
+**2x LDO Voltage Regulators?**
+Yup! The first one is for the general operation of the board and the ESP32-S2, RAM and Flash. 
+
+The second LDO is for you to use to connect external 3V3 modules, sensors and peripherals, and it has programmable EN control tied to GPIO21 + it’s connected to the deep sleep capabilities of the S2, so if the S2 goes into deep sleep, the 2nd LDO is automatically shut down for you!
+
+**Pre Release Hardware?**
+The board design is final and it works great. But right now, the only way to develop on it is with an unfinished pre-beta IDF and there is no CircuitPython, MicroPython or Arduino support. So I can’t really call this board final until I at-least have a feature complete IDF to test it against :)
+
+**Why is the board $26?**
+Well, these are a short run of pre-production boards and buying components in small quantities is THE most expensive way to buy them. That will change when I go into production, and I expect the final production boards to be around $20.
