Crate umsh_bsp_wio_tracker_l1 

Board support for the Seeed Wio Tracker L1 / L1 Pro (nRF52840).

Composes umsh-bsp-nrf52840 with the Wio Tracker L1 family’s pinout and on-board peripherals.

The same crate covers the L1, L1 Pro, and L1 Lite variants, which share a pin map. The L1 e-ink variant has a different display path (SPI1) and would warrant a separate BSP crate.

What lives here:

• [display]—SH1106 OLED over I²C (SDA=P0.06, SCL=P0.05, addr 0x3D)
• [power]—PowerControl bridge, shutdown signal, and the SAADC battery monitor (AIN7/P0.31, divider gated active-high on P0.04)
• [buzzer]—piezo on P1.00, driven straight from PWM
• [gnss]—Quectel L76K standby control (P1.09); the module has no rail this board can cut, so its backup domain is the board’s clock
• [platform]—the Platform type bundle used by the console bringup harness

Concrete pins for the radio (SX1262 on TWISPI1 plus the external RXEN on P1.08), the user LED (P1.01, active-high), the Back button (P0.08), and the four-way pad with its center press (P1.04, P0.12, P0.11, P1.03, P1.05—up, down, left, right, press) are chosen by the firmware, following the pattern the other nRF52840 tracker boards use. All six switches are active-low with pull-ups.

Host I²C includes the Grove expansion bus. Not yet wired: the QSPI external flash.
