Introduction The FeelChip D is PCBA board designed for the haptic industry. It has 3 motor channels and 5 touch channels. The FeelChip D is equipped with: 1. 2. 3. 4. 5. 6. a LIPO charging unit a. 5 volt RGB LED light a. Charging (red) b. Almost empty (blinking red) c. Bluetooth (blue) d. Charged (green) Press Button a. Turn the device on/off b. Switch through patterns Programmer a. Pin to program the ESP32 MPR121 a.
Programming 1 The FeelChip-D-2p can be programmed with a Tag connect TC2030-IDC-NL or a 2 TC2030-MCP-NL on the small footprint PCB Tag-Connect PAD. Alternatively it can be programmed using the test pads with the aid of a Pogo Pin test setup. There are two methods to programming the FeelChipD: , 1) Via Tag-Connect PCB pads 2) Via Pogo-Pin Test pads Tag-Connect PCB Pads For manual programming, the Feel Robotics ESP32 programmer is used which is only 3 compatible with the TC2030-MCP-NL cable.

USB Battery Charger To test if the battery charger5 is working 5V is applied over TP3(5V) and TP2(GND). If pads +(VBATT) and –(GND) will have approx. 4.2V across the battery charger is functioning properly. LDO Power To test if the battery charger6 is working 5V is applied over with POGO pins connected to TP3(5V) and TP2(GND). If POGO pins connected to TP(1) or TP9(2V8) will have 2.8V across it to TP2(GND) the LDO is functioning properly.
FCC information The OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed. Host manufacturer (OEM) is responsible for ensuring that the host continues to be compliant with the Part 15 subpart B unintentional radiator requirements after the module is installed and operational. The grantee's FCC ID can be used only when all FCC compliance requirements are met.
