+# Air mouse
+
+This project is aimed at replacing/open-sourcing the Logitech presenter. It also contains some features not found on the Logitech Spotlight.
+
+I used a **Seeed Studio XIAO nRF52480 Sense** board, but it required some BSP modification to work with SoftDevice S140 7.3.0. Namely the memory layout:
+```c
+/* Linker script to configure memory regions. */
+
+SEARCH_DIR(.)
+GROUP(-lgcc -lc -lnosys)
+
+MEMORY
+{
+  FLASH (rx)     : ORIGIN = 0x27000, LENGTH = 0xED000 - 0x27000
+
+  /* SRAM required by Softdevice depend on
+   * - Attribute Table Size (Number of Services and Characteristics)
+   * - Vendor UUID count
+   * - Max ATT MTU
+   * - Concurrent connection peripheral + central + secure links
+   * - Event Len, HVN queue, Write CMD queue
+   */ 
+  RAM (rwx) :  ORIGIN = 0x2000E000, LENGTH = 0x20040000 - 0x2000E000
+}
+
+SECTIONS
+{
+  . = ALIGN(4);
+  .svc_data :
+  {
+    PROVIDE(__start_svc_data = .);
+    KEEP(*(.svc_data))
+    PROVIDE(__stop_svc_data = .);
+  } > RAM
+  
+  .fs_data :
+  {
+    PROVIDE(__start_fs_data = .);
+    KEEP(*(.fs_data))
+    PROVIDE(__stop_fs_data = .);
+  } > RAM
+} INSERT AFTER .data;
+
+INCLUDE "nrf52_common.ld"
+```
+in `cores/linker/nrf52840_s140_v7.ld`
+
+You can use the `web-config.html` page to configure this device.
