#59865 The ESPLocalizer board is a spin off of the ESP8266 development of CNLOHR of Youtube fame. The esplocalizer-tight design is open source and leverages the versatility of the ESP 8266 microprocessor and WiFi along with the 10 degrees of freedom sensors.
The board has 4 main components:

ESP-12F WiFi module is developed by Ai-thinker Team. core processor ESP8266 in smaller sizes of the module encapsulates Tensilica L106 integrates industry-leading ultra low power 32-bit MCU micro, with the 16-bit short mode, Clock speed support 80 MHz, 160 MHz, supports the RTOS, integrated Wi-Fi MAC/BB/RF/PA/LNA, on-board antenna.

BMP280 is an absolute barometric pressure sensor especially designed for mobile applications.

LSM9DS1 is a versatile, motion-sensing system-in-a-chip. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer – nine degrees of freedom (9DOF) in a single IC.


STBC08 is a constant current/constant voltage charger for single-cell Li-Ion batteries.

These board will be available on eBay in the near future.
