BME680 breakout :: INTERFACES, PADS and SOLDER JUMPERS
I2C and POWERING INTERFACEIn the left edge of the top PCB side, top to bottom:1. Vin - POWER IN 3.3V / 5V (default) * 2. 3V3 - Vdd - LDO output (default) / LDO bypass IN ** 3. SDA - I2C SDA [default, pulled up at Vin]*** 4. SCL - I2C SCL [default, pullup up at Vin]*** 5. GND - POWER and I2C GROUND * Default, the I2C reference voltage follow the Vin voltage. If your board (Arduino/other) it's 5V compliant, connect +5V to Vin. Similar, for 3.3V compliant board(RPI/Arduino)connect 3.3V source to Vin. ** 3.3V voltage it's available on Vdd PAD, if Vin it's connected to 5V. Bypass LDO - see schema and read docs. *** Default, the I2C reference voltage follows the Vin voltage! Read bellow about I2C reference voltage and s1 solder jumper. SOLDER JUMPERSs1 : I2C reference [Vin or 3V3-bypass], default Vin *s2 : RESERVED s3 : BME680 I2C address [0x76/0x77], default 0x76 * * Read about s1 and s3 functionality bellow. SIGNALS INTERFACE and MARKINGIn the left edge of the bottom PCB side, top to bottom:6. RESERVED 7. RESERVED 8. RESERVED 9. RESERVED nc. NOT CONNECTED * Taking a look at howto posts and inside software examples may be quite helpful. Observe the sensor breakout marking on PCB board (here, BME680 sensor it's marked as populated). |

BME680 breakout :: solder jumpers description; power scenarioss1* - I2C reference voltage selector - shipped with circuit 1-2 closed and circuit 2-3 open (default mode). In default mode, the I2C reference voltage follows the voltage applied to Vin! Default mode use cases: - shield/MCU it's 5V compatible ==> connect Vin at 5V; the I2C reference it's 5V! - SBC/shield/MCU it's 3.3V compatible ==>connect Vin at 3.3V; the I2C reference it's 3.3V!. Alternate mode - I2C reference voltage follows the Vdd voltage! - modify s1 as: 1-2 circuit open, 2-3 circuit closed [carefully interrupt/cut the circuit line between pads 1 and 2, and solder over pads 2 and 3]. Alternate mode scenarios: - apply 3.6-7V to Vin. The I2C reference voltage it's set at 3.3V! Also, at Vdd pad (LDO output) 3.3V (up to 100mA) it's available for third part powering (anyway, try to keep the sunk current as low as possible, in order to avoid thermal errors). - keep Vin not connected. Apply 2.8 or 3.3V to Vdd (the LDO it's bypassed). The I2C reference voltage it's set at voltage applied to Vdd pad! s3 - BME I2C address - default circuit open, BME680 having 0x76 as I2C address. Solder over s3 pads [circuit closed] in order to select the alternate I2C address [0x77]. * Consult s-Sense block schema for more information. See projects/how to section. |
