RE-Mote Revision A¶
Support for the RE-Mote board Revision A.
The RE-Mote has three versions, a first prototype A (remote-pa) only distributed to beta testers, its following revision A (remote-reva), and the latest revision B (remote-revb) which are commercially available. The following section focuses on the revision A.

Components¶
| MCU | CC2538 (ARM Cortex-M3 with on-board 2.4GHz radio) |
|---|---|
| Radio | Two radio interfaces (IEEE 802.15.4): 2.4GHz and 863-950MHz |
| RP-SMA connector for external antenna (with a RF switch to select either 2.4GHz/Sub-GHz radio) | |
| USB-to-Serial | CP2104 |
| Peripherals | RTCC, built-in battery charger for LiPo batteries, External WDT (optional), Micro-SD |
| Others | RGB LED, power management block (150nA when the mote is shutdown) |
Porting status¶
In terms of hardware support, the following drivers have been implemented:
CC2538 System-on-Chip: UART Random number generator Low Power Modes General-Purpose Timers I2C/SPI library LEDs Buttons RF 2.4GHz built-in in CC2538 RF switch to programatically drive either 2.4GHz or sub-1GHz to a single RP-SMA
And under work or pending at cc2538 base cpu:
Built-in core temperature and battery sensor. CC1200 sub-1GHz radio interface. Micro-SD external storage. ADC USB (in CDC-ACM). uDMA Controller.
Layout¶
Flashing¶
The RE-Mote has built-in support to flash over USB using the BSL. Previous versions required to unlock the bootloader by manually pressing the user button and reset button, but the current version handles the sequence with an on-board PIC, so automatically unlocks the bootloader upon flashing.
e.g.
1 2 | Bash
$ make BOARD=remote-reva flash

Pin out and connectors¶
RE-Mote on-board connectors pin-out¶
The RE-Mote uses the Molex 5-pin WM4903-ND male header connector to connect digital sensors based on I2C and SPI protocols, as well as other sensors or actuators you may need to connect. The pins are 2.54 mm spaced and the connector has the following pin-out:
