CV in complex ways. CV in to pause the clock oscillilator an external CV-to-pulse-rate module? Is this even useful? - Seven-segment display. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled CV offset module - add a voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a precision give to the previous module with integral chip antenna (http://ww1.microchip.com/downloads/en/DeviceDoc/60001380C.pdf Cypress EZ-BLE PRoC Module (Bluetooth Smart) 21 Pin Module Digi XBee SMT RF ESP WROOM-02 espressif esp8266ex 2.4 GHz Wi-Fi Bluetooth external antenna espressif 20*15.4mm 2.4 GHz Wi-Fi https://www.espressif.com/sites/default/files/documentation/esp32-s2-wroom_esp32-s2-wroom-i_datasheet_en.pdf 2.4 GHz Wi-Fi and Bluetooth combo chip https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32_datasheet_en.pdf Single 2.4 GHz Wi-Fi and Bluetooth combo chip Single 2.4 GHz Bluetooth ble zigbee 802.15.4 thread nordic raytac nrf52840 nrf52833 Bluetooth Low Energy Module ble module st bluetooth Taiyo Yuden NRF51822 Module Bluetooth RF transceiver SMD style RF transceiver THT style https://www.rfsolutions.co.uk/downloads/1456219226DS-ZETA.pdf Laird Technologies BMI-S-203-F Shielding Cabinet SMD 30x30mm WE-SHC Shielding Cabinet Two Piece SMD 38.10x25.40mm (https://assets.lairdtech.com/home/brandworld/files/Board%20Level%20Shields%20Catalog%20Download.pdf Laird Technologies 97-2003 EZ PEEL Shielding Cabinet Two Piece SMD 32.00x32.00mm (https://assets.lairdtech.com/home/brandworld/files/Board%20Level%20Shields%20Catalog%20Download.pdf Laird Technologies BMI-S-207-F Shielding Cabinet Two Piece SMD 26.21x26.21mm (https://assets.lairdtech.com/home/brandworld/files/Board%20Level%20Shields%20Catalog%20Download.pdf Laird Technologies BMI-S-104 Shielding Cabinet THT.
