# RAK Wireless RisBlock ## Docs https://docs.rakwireless.com/Product-Categories/WisBlock/Quickstart/#wisblock-base-2 GPS module: Supposedly "Install in slot A only" but I think installing on the back would fit better with the OLED. FIXME. https://docs.rakwireless.com/Product-Categories/WisBlock/RAK1910/Overview/#product-description ST KPS22HB baro sensor https://docs.rakwireless.com/Product-Categories/WisBlock/RAK1902/Overview/#product-description OLED https://docs.rakwireless.com/Product-Categories/WisBlock/RAK1921/Overview/#product-features Must be installed on the front for the I2C wires to lineup Solar enclosure https://docs.rakwireless.com/Product-Categories/Accessories/RAKBox-B2/Overview/#product-description Base datasheet (for GPIO mapping) https://docs.rakwireless.com/Product-Categories/WisBlock/RAK5005-O/Datasheet/#specifications CPU module carrier (rak4631) https://docs.rakwireless.com/Product-Categories/WisBlock/RAK4631/Datasheet/#specifications ## TODO > 3V3_S is another 3.3 V power supply, it can be controlled by the MCU in order to disconnect the power sensors during idle periods to save power. 3V3_S is controlled by IO2 pin on the WisBlock Core board. Set IO2=1, 3V3_S is on. Set IO2=0, 3V3_S is off. * DONE solder header * DONE attach antenna * get building (LORA disabled) * DONE FIX LEDs * DONE FIX BUTTONs * DONE FIX I2C assignment * FIX LORA SPI * FIX GPS GPIO assignment * Disable Bluetooth * Disable LORA * Boot * Enable LORA but no TX * Enable LORA TX * Enable bluetooth * Relase as standard part of build (including UF2s) * Make this doc into a nice HOWTO: what to order, how to connect (which device in which slots), how to install software * Setup battery voltage sensing * Set bluetooth PIN support * Confirm low power draw * send in PR to https://github.com/geeksville/WisBlock for boards define *
